34 pict 3 idle jet size

Once the jet is loose it sort of falls on it's side, so then I use the screwdriver to nudge the jet out along the trench to the plug hole in the side (rather than using needle-nose pliers). Use stock vacuum line from air-intake #4 for CDI control unit. On the H303/1 it is often oversized too - a 65, used to stop the engine stalling at low rpm as the main jet supplied with these is often VERY lean 117.5 or 120. Now unscrew it exactly 2-1/2 turns. Just start off with a larger than normal size (150 maybe) and use the screw to increase/decrease the actual hole size. The carburetor was a little "leaky" around the shafts. So there is a HUGE difference in hole size compared to the main fuel jet. When used with the heavy bodied Type 2 vehicle and a vacuum distributor, it should work well with a 60 or 65 idle jet, 125 (or just maybe 127.5) main jet and a 125 air correction jet. Our ability to respond to emails is greatly hampered by being under-staffed during this downsize transition time. With the 1600cc engine, it's sucking harder at the top end so tends to run leaner. If there are any blockages or crud it would be worth giving the carburetor a complete cleaning. The exhaust system peashooters started turning black inside as soon as I put the larger jet in. December 20th, 2019 - Peugeot 205 User Manual Solex 32 34 Z2 carburettors 28 4c Idle speed adjusting screw location 1 on the Weber 32 If you have a proper vacuum distributor, it might be possible to make the main jet a little bit smaller (X125 is the next size down from X127.5), but this will not make very much difference in the fuel consumption. When using the 30PICT or H30/31 carburetor on a twin port manifold and any vacuum distributor, change the jets to X125 or X127.5 main, 55 idle, and leave the air correction at 125Z. The fuel flow through each jet is determined by the airflow which creates a low pressure area near that jet. Be sure to check your engine's fuel pressure and ignition system. This is not correct. Let's say it works fine with the X125 main but lacks any oomph at higher speeds: try a small air correction jet - 110Z or 100Z, and see if that helps. We have had great results with these factory bench tested carburetors. Golf Mk1 > Volkswagen Workshop Manuals > Power unit > 34 PICT, Keihin carburettor and ignition system > Mixture preparation carb. Unscrew the idle jet from the carburetor and the cut-off solenoid, and blow through it. The other one (pointing straight out to the right side of the car) is the power jet, which feeds additional fuel at high throttle/high rpm. . If the idle cut-off valve fails in the shut position, the car will still run (roughly) on the main jets but will stall as soon as you take your foot off the throttle. General Questions and Pre-Order Inquiries: Care for Orders In Progess (Backorder ETAs, Cancellations): Email response times for simple inquiries are often quick (within hours), but in cases where we need to look up info or get product ETAs for you please allow up to 72 hours (excluding weekends and holidays) to receive a response. Assuming a vacuum distributor, the 34PICT/3 carburetor is usually jetted with a X127.5 main jet, and 100Z -120Z air correction jet. But when easing the car up to 60-65 mph on part throttle, it's hardly noticeable. The main jets also fit EMPI and Brosal Kadron 40/44EIS Carburetors. The optimal stiochiometric (balanced) ratio is 14.5:1 -- that is, 14.5 parts air to one part fuel. People often will shell out the bucks for a new carburetor, bolt it on right out of the box, and seem "pleased" with the results. Any auto supply store can sell you a little T-shaped adaptor that will fit on the terminal, with three "wings" (if you will) to which the three black wires can be attached. In these later models, you can easily change the jet with a medium screwdriver either with the top of the carburetor removed or with the carburetor completely off the car. The extra advance helps reduce the 009 flat spot just a little. Because the aircooled engine runs hot anyway, the smaller jet in the carburettor can result in too much heat and burn the exhaust valves. If the engine is stumbling at 2000 RPMs and lower, then you need to richen up your idle jet (go to a larger size) - but check carefully for air leaks around the throttle shaft first!. Solex 34 pict 3 jet size. Where the early style carburettor has the idle cut-off solenoid on the RIGHT side of the carburettor, that solenoid sits in the back of the idle jet. If it takes 4 1/2 to 6 turns to peak, go up a size or (1/2 size if you. Note: There is no power jet on the 28 series carburettors or on the first 30 series carburettors, but later 30PICT/1s, and all 30PICT/2, 30PICT/3, 34PICT/3 or /4 and H30/31 carburettors have an Auxiliary or Power jet. Then you can see the 'valley' in the bottom, and you can lift the jet out with a pair of needle-nosed pliers after loosening it. Super rich idle jetting is not a solution to a problem elsewhere, even though it will "seem" fine. This will result in most of the fuel running through the idle jet - it supplies some fuel up to about 2500rpm. Our 74 Super has a tube running from the 34 PICT 3 down, and is . The 34 PICT-3 was used on the Volkswagen "Beetle" from 1971 until 1974. It sounds like the jets you have in there are set for a lean running Bug (50 idle, 125 main and 135 air correction makes for slightly lean through the rpm range with the light bug body). And fuels! So I replaced it with a 30 PICT-3 carburetor in a good condition. Note: Dave found that NONE of the several top-to-body gaskets provided in the kit was the right size or configuration for his carburetor (he was possibly sent a kit for the earlier series carburettors). If I can't iron it out with the high speed jet I'll start on the idle jet. We did a run of these, but due to a limited supply of the quality Bocar 34-3 carbs, we do not know how long we'll have these carburetors! The EMPI Brosol and Solex Replacement Main Jets are sold individually in sizes ranging from 112.5 to 170. Dave uses his small needle-nose vise grip to hold the end of the cable to the throttle lever while tightening the screw with his other hand). Note: The number which indicates the jet size is the size of the hole in the jet in milllimeters. The idle cut-off valve is not strictly a "jet," but this is a good place to discuss it. This jet is critical to engine flexibility and economy. Do not allow cleaning solvent to come in contact with skin. AU $0.86 (approx 0.48)Australia Post International Standard. SKU: 43-5040-7. $7.99. Main jet should be around the 130-135 area. In both cases, when running the 009 distributor, set the accelerator pump for maximum squirt. If you have a 009 (centrifugal advance) distributor, you may find that the spark plugs still seem a little dry/burnt looking at medium speeds , or the car lacks acceleration in the mid ranges. A loss of power is the result -- about 58hp instead of 60hp. 2060 Solex Pierburg Kadron idle jet; 2056 Solex Air corrector jet; S61634017 Solex Z1 - Z2 Float; Solex float PBIC PIBC PICT; Solex float PICT; 6200018 Solex Needle valve size 160 Fiat 124, Alfa Giulia; 52844 Solex Pierburg needle valve VW PDSIT PICT DIDTA DIS; As we learn more, we will include it here. If the fuel/air mixture is too lean, the engine will run very hot, stumble, and misfire -- and burnt valves can be the result. Setting the idle screws (B): Tighten the screw until it touches the carburetor lever. On the /3 and /4 carburetors - it looks like a bolt with a tiny silver plug in the center. Carbs help Solex 32 34 Z2 Overclockers UK Forums. Nomenclature Since Aircooled.Net has no control over product installation, we will not be held liable for any consequential costs or damages associated with products purchased. With the larger main jet, you might also need to consider a size 50 idle jet in lieu of the normal 55. All products purchased should be inspected, measured, cleaned and properly assembled prior to installation. That's fine for modern cars with engine computers which can adjust the mixture on-the-run, but what about our old fixed-jet carburettors? Which one is which one? In other words, it's extremely crucial for in-town driving. But optimum performance and MPG will be achieved when you use a wide band and tune the carb for 16:1 A/F on cruise, and 13:1 over 1/2 throttle. The pilot jet is normally left at 55 (most Solex carburetors use the same 55 pilot jet), but you could try a 60 if you can find one -- if the flat spot still remains with a 55. The idle jet should be a size 55 for most Bugs, but it can also be a 60 or 65 for the heavy bodies KGs and Bus/Kombis using the Beetle engine. general exploded view of the 34PICT/3 Carburetor is shown in the Pilot jet cutoff valve: 3: Carburetor upper half: 15: Gasket: 27: Circlip: 4: Float needle valve: 16: Rebuild. The 30PICT/2 carburetor has a fuel idle cut-off in the right side of the carburetor but the 30PICT/3 and the H30/31 should have an air idle cut-off in the left side for the carburetor (same as the larger 34PICT/3) -- that was part of the change to the /3 carburetor version -- moving the idle cutoff valve to the left side. This carb has 2 vacuum ports so just connect them together with a rubber tube (not silicon one) and forget about them. Items that are not expected to be restocked within 2 weeks WILL BE AUTOMATICALLY CANCELLED. E85 - forget it for the aircooled VW engine! Rob responded - A X120 main jet would make it run leaner, and it sounds like it is too lean already. But engines do differ a little, and the sizes above are "ball park" figures rather than definitive. MSRP Price: $9.11 You Save 12%. Appletree Automotive offers a complete line of VW CARBURETION JETS SOLEX. . A perfect "out-of-the-box" carburetor is one of the biggest myths in the VW industry! Rob replaced the air correction jet with a 140Z, and at low-middle speeds there is no discernible effect. Basically, the emulsion tube changes the diameter and location of small holes in it's body. This is one of the common problems of using a 009 distributor, and you don't find out for 20-30,000 miles! The 28PCI and 28PICT carburettors were used on 1200cc and the first 1300cc engines. The 1600cc DP can flow more air than the 1600cc SP and smaller engines. In most cases we are able to honor advertised price, but in the RARE case a substantial price increase occurs, you would be notified and given the option to cancel. following diagram. I would stick with the 34 pict 3 carb with the dual port. The effect is clearly noticeable from 3000 RPM upwards (just under 60 mph), and probably a little lower than that. More throttle does make it go away. Or should I open what I have or rob from a newer model? Home . Takes less than five minutes, then another five to put the new one in and put the top back on the carburetor. Air is much less dense than gasoline, so that makes sense. Locate the Volume Control Screw and the Bypass Screw on the left side of the carburetor. The 34PICT/3 carburetor is usually used on 1600cc or larger engines. by vwlover77 Fri May 05, 2017 6:58 pm. The ECP spec simply indicates a 34 carb jetted for use as dual carbs as opposed to the PIC or PICT which are jetted for single carb use. The idle jet should be a size 55, and power jet size 65. Do you know what size high speed jet you have? The Power Fuel System Dispensing Nozzle for the VW 105-1 would be 0.50 with no check ball. All the plugs look the same -- black and fluffy, telling me a rich condition. But if you find a solid brass bolt, the main jet is further in the float chamber (later models) but still right in the back of it on the right-hand side. Orders are processed in the order that they are received and order fulfillment time varies. Then video is intended as an example.. If you are using a 009 distributor with a 30PICT carburetor on a 1600 cc DP manifold, the main jet should be X130 or X132.5 and the air correction reduced to about 100Z. to start at sea level. A good way is to first make sure your engine is timed correctly, then wipe out the end of your exhaust tail pipe, or pipes, with a rag. JET KITS are available if needed. Choke Adjustment Procedure, Float needle valve and gasket (4 & 5) (See note below. Carburetor Installation. A clean plug with a light grey/tan look means the mixture is about right. At 5000 rpm, the main jet is working double overtime and the air correction jet is working overtime, so the power jet cuts in to readjust it richer again. When you work out the area of the hole in each jet, the steps are roughly 2% increase in fuel flow for each size up (X125 to X127.5 for example). Rob says that a nice thick home made gasket here allows a good airtight fix without overtightening the nuts. The larger size 65 idle jet helped the 30PICT/3 and H30/31 carburetors overcome the very lean main jet at idle and low speeds, and thus help to reduce the "bogging" problem. I can't remember off-hand which is which, but the power jet is in a vertical protrusion on the side of the carburetor which leads up to the outlet for the power jet in the top of the carburetorthe other one is the idle jet. Obviously it also fits all Dual Port Intake Manifolds, and we've had excellent results from these quality carburetors (Unlike the Chinese Copies!!!). On some models (the H30/31 for example) it is angled slightly towards the back of the car. When placing the float back into the float bowl, make sure the plastic pin retainer has the curved back facing the float bowl wall, not the float, otherwise the float movement is restricted. Peugeot 205 Manual . As indicated previously, the VW engine actually runs better at fractionally rich settings (ideally 13.8:1 rather than 14.5:1 according to Bob Hoover who did lots of testing), but they are usually jetted a little leaner than that, so the X127.5 is really a minimum jetting for the 1600cc engine. Checking and adjusting cold idle speed =>page 22-53 Throttle valve positioner However, the loss of power as you pass 60mph is noticeable with the 140Z, whereas there was lots more power for middle-higher speed acceleration with the 125Z. Delivery: Estimated between Mon, 6 Mar and Wed, 15 Mar to 23917. Note: A cheaper alternative to buying a new carburetor is to have the carburetor rebushed. We are now only fulfilling order requests only for items that we have in stock OR that we know can be acquired within a defined timeframe. And the second issue is the presence of Ethanol (alcohol) in gasolines. If you have a 009 distributor (no vacuum canister on the side), the main jet should be about X130 or X132.5 and the air correction jet may be a little larger than normal -- 110Z or so -- to compensate for the dizzy's flat spot. Dispatched today if paid within 1 hr 21 mins See details. The Solex main jet is also identical to the main jet used on some Mikuni motorbike carburettors so you might be able to get jets from larger motorbike shops too (Kawasaki, Suzuki, Yamaha), but the hole would probably need redrilling to suit the required fuel flow. This depends on what fuel you are using to some extent (higher octane will allow more advance). Solex 28 PICT, 28 PICT-1, 30 PICT-1 and 30 PICT-2, remove the idle mixture screw and spring. Starts right up and runs great. To compensate for this, an air correction jet is inserted in the fuel delivery circuit after the main jet, which starts to add air to the fuel emulsion as the airflow increases. You will find the Pilot Jet Valve in the same location as on the German 30 Pict-1 Carburetor. 34 PICT Carburetor Combination, Automatic Choke Discussion and Adjustment Procedure. If you try removing the idle shut-off valve and the air correction jet (the brass bolt head in between the float bowl and the main throat) and the idle jet itself, and then blast air through the passages in both directions, that might get it. Brosol/Solex Idle Jets .40. The fuel screw setting at idle trims the pilot fuel, and considering the fuel screw ends up at 1.5/1.75, the 1/8 throttle position (all 100% pilot flow) will be rich. Check the jets in the carburettor - if you have a vacuum distributor (you didn't say which sort you had), then the 34PICT/3 carburetor should have a 55 idle (right side of the carburetor. the chart. You will see a black wire coming into the positive terminal on the coil from fuse #12, which receives power from the ignition switch, so the valve opens whenever the ignition is on, allowing the idle fuel to flow. PLEASE NOTE: You are NOT CHARGED for out-of-stock items. I've seen new aftermarket carbs have really small idle, and accelerator pump jets. does anyone have a link to a graphic that explains where it is on the carb? Float pin retainer (7) The condenser is 1 237 330 251. You'd think the jet sizes would follow the capacity more closely, but they don't. Rob wrote in this regard - See our article on Reading Spark Plugs. following topics related to the 30 PICT/2 and 3 and 34 PICT/3 and 4 Solex 34 PICT 3 VW air cooled carburettor replacement; . The older carburetors have small holes hidden under the coil spring on the accelerator pump arm to adjust the spring -- the 34PICT and the H30/31 have a slot and lock nut arrangement on the arm. Make sure the old one you took out stays in good shape so it can be reused. If this is the case, try a larger size main jet -- size X127.5 1200/1300/1500cc engines. With the idle cut-off valve working correctly, hot spots in the cylinders don't occur as readily, since there is no fuel available to keep the engine running once you turn off the ignition. Same with the carburetors in general, so adjustments become essential. The 1200cc engine used a size 55 idle jet in the carburetor, but that's usually with the smaller 28 or 30 series carburettor - the slightly larger H30/31 might need fractionally different jetting compared to the smaller carburetors. The VW 105-1 Air Correction Jet would be 125z. It appears to replace the plug in the bottom of the 30 PICT/1 carburetor float bowl, which has the jet mounted inside and in line with that hole. But we continue to endeavor to answer email inquiries as best we can. If not, I find that "canned air" (like Ultra Jet or similar) works pretty well. I've been running my '68 Bug with the X127.5 main jet in the smaller carburetor, and he's running a tad rich. . With a leaner 140Z air correction jet in the carburetor) I got 11.6 km/l (27.5mpg US). Rob responded - If you still have a vacuum distributor - yes. Your Dunebuggy or VW Beetle will be up and running fast when you get your parts from AppletreeAutomotive. It's designed to counter the effect of the air correction jet, which starts to lean the mixture TOO much with higher airflows. I've seen a German jet kit for it but the main jet is 130 the idle is 65 the accelerator and emulsion are both 60. Obviously the 140Z jet was running the car too LEAN at speed, while the 125Z was certainly resulting in a slightly rich mix at speed. But optimum performance and MPG will be achieved when you use a wide band and tune the carb for 16:1 A/F on cruise, and 13:1 over 1/2 throttle. Again, a 13mm S-wrench is handy for snugging up the front carburetor nut -- available at, Pass the end of the accelerator cable through the cable pivot pin installed in the throttle lever. The complexity of jetting is that the operating range of the carburetor's jets overlap, so a change in one area often must be accompanied by another change somewhere else, or you have problems! can find them - rare!). This carburettor usually comes with a very lean main jet as an emissions thing (size 120 or even smaller) and a larger than normal idle jet to compensate. Accelerator pump diaphragm (24) Ethanol contains USED oxygen which canoot be burnt again, so adding ethanol to gasoline/petrol, reduces the amount of energy per litre/gallon. jet - aux idle speed fuel 4. cover -with spring and heater element 25a. Rob's note regarding modern fuels: There are two major issues with modern fuels. I have lowered the fuel pressure down to 2.5 psi and checked the float bowl fuel height. Note: Dave found that none of the gaskets in his kit fit his carburetor. Then if you need a fatter idle go up to 57.5, then 60. Ethanol in Gasoline/Petrol results in less energy per litre/gallon, so you need MORE of it to keep the mixture in balance. So be sure to remove the gasket and store it carefully. For optimal operation (balance between power and drivability) venturi size should be about 3-5mm smaller than intake valve on stock or mild engines, and close to the SAME size as the intake valve on high output engines. Rob provided further explanation: The idle circuit is behind the main jet - the fuel flows THROUGH the main jet to get to the idle circuit. 2 of 2 people found the following review helpful. The air correction jet prevents the mixture going over-rich at high rpm (again, smaller numbers means richer for this jet). With lean jetting you are likely to need more throttle and have slightly worse fuel economy - using the slightly richer settings I'd suggested above will give you a little more power and a cooler running engine, so hopefully fuel economy will improve a little, but don't expect too much - fuel economy with the heavy Type 2 body is never very good. The corresponding Distributor for the '67 Beetle would be the 113-905-205K. Hey, use the stock jet size, which is 125 for the 34 PICT-3. My distributor is a vacuum advance (with a centrifugal?). The 1200cc engines usually used a X120 or X122.5 in the 28PICT carburetors, the 1300cc engines used either X122.5 or X125 in the 30PICT carburetors, the 1500cc engines usually used a X125, and the 1600cc engines usually need a X127.5 in either 30PICT, H30/31, or 34PICT, but MIGHT get away with an X125 in the smaller 30PICT and the H30/31. Turn the ignition on (but do not start the engine). The timing is set ATDC. Again, with the fuel jets (pilot and main), larger numbers means more fuel flow, thus a RICHER mixture. It's a problem VW recognized very early on (since the aircooled engine has very hot heads and hot-spots were therefore more likely than in water cooled cars), so the fix was to add the cut-off solenoid to the carburetors. It's actually much easier to do if you remove the top of the carburetor and the float. PRODUCT IMAGES are representative only. With the air correction jet you have to go 3-4 sizes different to see a real difference, unlike the main jet where one size can make a big difference. These plates provide restriction and also atomize the fuel/air mix better for greater fuel economy. Could you help me with the jetting? If it doesn't open you won't idle! Jetting With the Centrifugal-Advance (009) Distributor, Tuning the 009 Distributor/ However we have found that a standard 13-mm combination wrench works just as well. For the 009 distributor and the 30PICT/2 carburetor, you need a X127.5 or X130 main jet and a smaller air correction jet - about 100-110Z. Dave replaced the main, idle and air correction jets so he knew what he had. This means that the main jet is sized to the engine capacity, rather than the carburetor size, and X127.5 is the more common size for the 1600cc engine, rather than say the X125. Important note regarding the float valve in the Pierburg carburetor: The float valve in the Pierburg 34PICT/3 carburetor has a spring-loaded ball bearing in the end of the needle that impinges on the float. If it's working, you'll hear a clicking sound as the relay pulls in. The air correction jet is also changeable. Carburetor Removal Use as much advance on the 009 distributor as you can -- 32 degrees advanced at 3500 rpm rather than 30 or 28, so long as the engine doesn't detonate (ping). Then remove a spark plug and read it (see our Spark Plug Reading Guide). Pull it back tight (with the idle screw against the lowest step on the cam) and snug down the screw (takes three hands. To explain, the main jet supplies the fuel, and it supplies too much as the rpms increase (a function of the increasing vacuum in the main venturi). Email care allows us to provide important service detail that can be later referenced by both the customer and our care staff. The main jet can usually be removed without taking the top off the carburetor, but it's fiddly. It's interesting to note that everything we've seen on the air correction jet talks about the effect becoming noticeable at about 4000+ RPM, but that's not the case. such as, how do you know what mixture you are setting, and if you are running the car too lean and hot, or way too rich? Useful experiment anyway. > Servicing Keihin carburettor>07.78 . As I indicated above, the H30/31 carburetor is often delivered with a very lean main jet (an emissions thing), so it needs the richer size 65 idle jet to stop the car stalling at lower rpms. The adjustable jet would work with any of the Solex carburetors which have the jet mounted horizontally inside the carburetor. It is still UNCERTAIN, but we may re-open a substantially downsized version of our store again in the Spring of 2023. And of course make sure that it's properly connected electrically to the connection on the coil where power is provided (the + connection) -- the lead can break off. For information -- the 1200cc engines originally came with a 28 PCI or 28 PICT carburetor, both of which have a 22mm throat. Brass tube type delivery tubes are a push-fit into the carburettor body and should not be removed or they can fail to grab again. I have a 52.5 idle jet in it, so it took about 4 1/2 turns to get max rpm ( thru a tach on my timing light). Bentley (page 20 of the 'fuel' section -- table of 'carburetor setting and jets') says the X130 was normal for '71-'72 34PICTs, and X127.5 was normal for '73-'74s (non-California models). See our Carburetor Overhaul Procedure. It's a complex problem that faces ALL open throat style carburettors. Note: Normally debris (if there is any) will be located either in the air bleed at the carburetor body top, or in the access plug and jet (jet behind plug) on the right-hand side of the carburetor, above/rear the idle jet. There are three (or four) removable jets. The auxiliary (power) fuel jet is a small brass jet screwed into the right side of the carburettor, sittin in a protrusion running up to the top. "N" on the schematic is the coil. Note: The manuals say that you should not remove the volume control screw, as it is set at the factory. We ONLY charge for items that are available to be shipped in a timely or reasonably reliable timeframe. 2. A sooty plug means the idle jet might be a little large. Please do NOT rely on PHOTOS while shopping as many of our products have selectable product options that may change the nature of the product being ordered compared to the representative photo. Also make sure the accelerator pump is set for full squirt, and is squirting straight down the throat past the opening throttle plate - not splashing on anything on the way. I think the original idle jet was a 50, but the replacement jet orifices (orifii?) Fillister head screw and lock washer (upper Note: The main jet feeds fuel, so larger numbers mean richer mixtures, but air correction jets feed AIR, so larger numbers mean leaner mixtures). 2-F7 emulsion tubes for the IDF. Immediate shipment of requested products is NOT guaranteed. Both clearances are essential; If the accelerator pump linkage rubs on either end, the throttle lever will not be able to return all the way to the stepped cam, the result being an excessively high idle that cannot be controlled with the bypass screw. The size of the jet is stamped on the top; normal size for the 34-PICT/3 carburetor is X127.5 (1.275mm diameter hole). E10 usually needs a larger main jet and might also need a larger idle jet. What you are mainly looking for is the condition of the carburetor. The air correction jet has the emulsion tube attached to it -- this "foams" the fuel before it's added to the airstream in the throat. See the discussion of jetting with the 009 distributor below for needed revisions to the jetting of the 34 PICT/3 carburetor in this application.
