I'd avoid Chinese stuff on eBay. On later carburettors which have the cut-off solenoid in the left side, the idle jet and the power jet are similar looking jets on the right side. 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. Then tighten further according to the chart. They might be available individually or in a set. I also have a stock carb rack but it appears to have water damage and one or more carb is seized. In addition, if you have a problem with a 55/60 idle jet, and you have the right main jet, and still have a hesitation regardless of accelerator pump adjustment, you need to play with your idle air bleed (what the fuel from the idle jet mixes with). PRODUCT IMAGES are representative only. IDLE JET .55 .65 .60 (d) VENTURII 40mm . Disconnect the electrical lead from the valve, then touch it to the connector again. I managed only 22 mpg on a highway (around 50-55 mph), and 19 mpg when I was driving around 60-65 mph. Aircooled.Net has them, and I think Gene Berg in the US has them too. The modern H30/31 carburetor replaces the 28, 30 and 31 series carburetors and can be used on 1200cc, 1300cc, 1500cc and 1600cc engines with appropriate jetting. 737-144. 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. If it doesn't open you won't idle! This is not correct. and 34-3 carb. The Perform the Idle Adjustment and Timing procedures. Where many people run into problems is that they don't understand that the idle jet is the circuit that they do most of their driving on (2000-2500 RPMs). Also check that the valve hasn't worked loose in the carburetor -- they do sometimes, and then work only intermittently. The air correction jet prevents the mixture going over-rich at high rpm (again, smaller numbers means richer for this jet). 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? The stock carb has a 26mm venturi. Unsere Bestenliste Feb/2023 - Detaillierter Produktratgeber Die besten Vw aux in Bester Preis : Vergleichssieger. Remove the brass plug with a hex head on the left of the carburetor -- bottom of the float bowl (all the fuel in the carburetor will rush out). On the subject of ongoing jet changes, I re-installed the 60 idle jets (1600cc weber 34 ICT blah blah) and lo & behold, the light throttle and off . Carburetor Cleaning the air correction jet is probably OK as either a 70 or 80 (remember, more displacement/larger carb, less correction needed). . The idle cut-off valve receives power from the positive (+) terminal on the coil (#15) -- see the schematic which shows this wiring arrangement. the 127.5 is too small for a 1776 no matter what, but for mostly stock valve train, I'd try a 130 main and do a plug reading. Take the car for a run at a modest speed - say 35-40mph. 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. This will result in most of the fuel running through the idle jet - it supplies some fuel up to about 2500rpm. Look down into the top of the carburetor to make sure that the screwdriver is squarely in the slot in the jet and that the threads line up squarely, then just screw it in (the small screw driver sits deep in the slot in the jet and helps line it up). 34 PICT-3 carb, SOLEX 34MM ; Fitment: Carburetor Fits For any 1600cc VW Air cooled Type 1 engines,such as: 1971-1979 Volkswagen Beetle, 1971-1979 Volkswagen Super Beetle, 1973-1974 Volkswagen Thing, 1971-1974 Volkswagen Karmann Ghia, 1967-1973 Volkswagen . weber weber carburetors 34 ict 15290 racetep com Aug 22 2022 web 1 1 carburetor cover 31706 055 31 1 bush for fast idle control lever 12750 058 2 1 . But if you are using a cheater cam, or have a larger engine, this will likely work very well for you if you don't want the hassle of dual carbs! The idle cut-off valve is not strictly a "jet," but this is a good place to discuss it. The Pilot Jet Valve (idle jet) would be the g55. It's a complex problem that faces ALL open throat style carburettors. You will find the Pilot Jet Valve in the same location as on the German 30 Pict-1 Carburetor. Regarding the 1776cc engine: the stock 34PICT/3 carburetor with a fractionally larger main jet and a fractionally smaller air correction jet to suit the higher air flow being asked of the carburetor should suit nicely. 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. Rob's note regarding modern fuels: There are two major issues with modern fuels. I've rebuilt the carburettor, and it did not help. Carburetor Installation. Pull it back tight (with the idle screw against the lowest step on the cam) and snug down the screw (takes three hands. Solex 34 PICT 3 VW air cooled carburettor replacement; . Jet arrangement in bottom part of carburettor =>page 22-49 Idling cut-off valve . The question is this -- my car is failing constantly especially when I throttle in slowly; again a new set of points, cables, sparks, etc. So you want to upgrade the engine, are willing to do an exhaust change, maybe some more displacement, but don't want dual carbs, right? Our last contact with Keith was some years ago. If this is the case, try a larger size main jet -- size X127.5 1200/1300/1500cc engines. if you look around to really get it right on! 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. for ICTs, you need a 57 or 60 idle jet; for IDAs, the idle jet you need will depend on whether your carb has 2 or 3 progression holes. Main jet plug seal (15) Main jet size 127#, Pilot Jet size 55 # MPN: Replace For OEM part Numbers 113129031K . Main jet should be around the 130-135 area. 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. If it takes 4 1/2 to 6 turns to peak, go up a size or (1/2 size if you. Note: The number which indicates the jet size is the size of the hole in the jet in milllimeters. But engines do differ a little, and the sizes above are "ball park" figures rather than definitive. Unscrew the idle jet from the carburetor and the cut-off solenoid, and blow through it. In other words, it's extremely crucial for in-town driving. We disassemble the carburetor, and bore the venturi to 28mm for more air! If you look at the two jets you can see that the (angled) idle jet sits in a protrusion (channel) which continues downwards under the jet, towards the idle and transfer ports in the throat near the butterfly. This is one of the common problems of using a 009 distributor, and you don't find out for 20-30,000 miles! Screw it in GENTLY until it bottoms. The condenser is 1 237 330 251. Which one is which one? following diagram. December 20th, 2019 - Peugeot 205 User Manual Solex 32 34 Z2 carburettors 28 4c Idle speed adjusting screw location 1 on the Weber 32 So, if you want to lean out the fuel/air mixture, you go bigger on the air jet, and vice versa. Here's the story: '68 bug with a ~'73 engine, 1600 dp, dual vac dizzy. Lastly, you have emulsion tubes to change "where" it's rich, lean, etc. 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). Free shipping for many products! As these plates restrict air flow, there is less vacuum to . The 30 and H30/31 carburetors were designed primarily for the 1300-1600cc single port engines, but you can get slightly better performance with the larger carburetors on a 1200cc engine, but only if they are set to run properly with the smaller engine. If it is any lower the choke may be staying on too long, or it may be stuck on and won't open at all. In most cases you can just leave the power jet alone. ; Replace Part Number: 98-1289-B, 113129031K.Dual Port Manifold only, Not for single port. We have had great results with these factory bench tested carburetors. Special Instructions Dave jetted his new carburetor as follows: main jet - X130; idle jet - 55; air correction jet - 80Z. The numbers are: 231 168 015, and 043 905 205 L in the second line. Rob's note: When removing the main jet, I use a small glass jar (pickle or baby-food jar) to catch the fuel from the brass plug - I hardly spilled a drop (I just allowed the plug to fall in to the jar), and used the fuel to refill the float bowl later. Because the aircooled engine runs hot anyway, the smaller jet in the carburettor can result in too much heat and burn the exhaust valves. Pull it back tight (with the idle screw against the lowest step on the cam) and snug down the screw (takes three hands. The smaller jets WILL NOT work with the 009 distributor. Jun 10, 2013 (Edited) cactu4r said: I've got a recently rebuilt 1600 DP, 34-pict-3, DVDA, and I am having the hardest time getting the engine to idle. Located in: Braunschweig, Germany. These carburetors come jetted "generally", and will bolt on and run. Could you help me with the jetting? Use stock vacuum line from air-intake #4 for CDI control unit. Fillister head screw and lock washer (upper For example, when used on a 1300cc engine with a vacuum distributor, the H30/31 should usually have a main jet of X122.5 and an air correction jet of about 140Z; but when used in a 1600cc single port engine, it should have a 125 main jet and a 125 or 130 air correction jet. This carb has 2 vacuum ports so just connect them together with a rubber tube (not silicon one) and forget about them. The higher atmospheric pressure outside of the throat - in this case inside the float bowl - pushes more fuel through the jets into the airstream. The old one for a pattern and a sharp hobby knife or box cutter works well. For a 1776cc engine with 009 distributor, 55 idle, X132.5 or X135 main, and air correct around 80Z should be close to the mark. Venturi Size. It is still UNCERTAIN, but we may re-open a substantially downsized version of our store again in the Spring of 2023. Brosol/Solex Idle Jets .40. 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. So VW chose this configuration. Note: Compare the new float valve with the old one. May 13, 2014 @ 5:57 am. 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. > Servicing Keihin carburettor>07.78 . 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. That terminal on the coil is just a convenient place to obtain power to these components. body (5). 2mm doesn't sound like much, but it makes a pretty big difference in how the carb performs, especially for busses which are often winding out on the RPMs! The idle jet sits in a protrusion running down to the bottom of the carburettor, and the power jet sits in a protrusion running up to the top of the carburettor, so it's easy to tell which is which. Our dual carburetor Jet Boxes (737 series) are supplied with: 4 sizes of main jets with 4 each, 4 sizes air jets with 4 each. Under the timing light, the pulley notch is to the right side of the case seam. Rob responded - A X120 main jet would make it run leaner, and it sounds like it is too lean already. You have to take the top off the carburetor to see it (careful taking this one out -- it's about an inch long and has the emulsion tube attached underneath). on a 1776. Reply to Phatman. For the 1600cc engine, you need more fuel flow, so a larger X127.5 main jet and 100Z or 120Z air correction jet are needed. None of these tests are definitive - just indicative. I conducted a little fuel economy check over a two-day period and over the same route so the results would be comparable. For example, the X130 main jet is a tad rich for the vacuum dizzy at sea level, so if the car is to be operated at a high altitude it will be running very rich, and you might get a smoother engine and less exhaust soot with an X127.5 or even an X125 main jet (the "right" size for 5000 feet altitude). Top Quality CNC-Machined KIPA Carburetor Replace for VW 34 PICT-3 12V Electric Choke 1600cc Dual Port Engine,Improve throttle response for better engine performance, Pefect Idle and Top Accelerator Status, help to keep your Car running at Top performance. You might want to drop a pilot jet size. Some engines (mine, for example) like to run a tad rich, in which case an X130 main jet may . On the /3 and /4 carburetors - it looks like a bolt with a tiny silver plug in the center. Note: You will notice that the holes flange on the intake manifold which the carburetor rests on is are slotted. With the larger main jet, you might also need to consider a size 50 idle jet in lieu of the normal 55. Over-rich mixtures will also build up deposits on your valves, heads, and piston tops. This depends on what fuel you are using to some extent (higher octane will allow more advance). I've been running my '68 Bug with the X127.5 main jet in the smaller carburetor, and he's running a tad rich. Following that is a listing of the parts, giving JET KITS are available if needed. Carburetor Reassembly Idle jet sizes of 70 or so will "run" on anything, but they don't run WELL (unless fouled plugs or 12mpg are your idea of "well"). following topics related to the 30 PICT/2 and 3 and 34 PICT/3 and 4 I have lowered the fuel pressure down to 2.5 psi and checked the float bowl fuel height. (Adapted from John Connolly's article on How to Jet Your Carburetor. This little ball bearing MUST be in place. The jet has a slot in the back so it can be loosened with a screwdriver through the hole where the plug was. Except for the fact that it won't idle! 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. First - Muir above was writing in the 1970s, before the USA changed their octane rating system, and also before Ethanol became common in fuels. We appreciate your continued support and understanding. 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. It's possible to develop partial blockage in one or more 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. 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. A loss of power is the result -- about 58hp instead of 60hp. Our 74 Super has a tube running from the 34 PICT 3 down, and is . 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. 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. E85 - forget it for the aircooled VW engine! For information -- the 1200cc engines originally came with a 28 PCI or 28 PICT carburetor, both of which have a 22mm throat. Aircooled.Net, Inc. is in no way affiliated or associated with Volkswagen AG or Volkswagen ("VW") of America. But we continue to endeavor to answer email inquiries as best we can. If you live at altitudes above 5000 feet, you also have to consider that, as high altitude results in the engine running rich (less oxygen in the air but the same fuel flow through the carburetor). general exploded view of the 34PICT/3 Carburetor is shown in the I think you are saying that the engine stalls (stops running) when you push the throttle pedal? A clean plug with a light grey/tan look means the mixture is about right. We can only give a guide here, as engine age, type of fuel, carburetor wear, etc. The carburetor was a little "leaky" around the shafts. Sent from my SM-G930F using Tapatalk The 30PICT/3 was used on the first (single port) 1600cc in 1970 in the USA (not in other countries), and the 34PICT/3 and /4 were used on all 1600cc twin port engines from 1971 onwards. Another question - The car runs terrible but it runs. Carbs help Solex 32 34 Z2 Overclockers UK Forums. . So a 34PICT/3 carburetor with an 009 distributor should be jetted with an X130 or X132.5 main jet, and an 80-100Z air correction. The sizes are stamped in tiny numbers on the heads of each jet. All information should be verified prior to use. 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 venturi sizes listed below are the sizes supplied by Weber in new carburetors. (Solex jets are marked with the hole size in mm, so a X127.5 jet has a 1.275mm hole - I'm not sure what numbering method Mikuni use). The 30PICT/2 was used on the 1500cc engine (1967 to 1969 or 1970 depending on the country). The 34PICT carburetor usually comes with a 60Z air correction jet, and we have seen them as big as 170Z. I played with the timing, the volume screw, almost everything, I even found a X120 main jet and tried that as well, but she's still failing. So how do you know which to use? jet - aux idle speed fuel 4. cover -with spring and heater element 25a. 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). We have seen advice to the effect that both the main jet and the air correction jet (and maybe others) must be replaced with larger ones in the 34PICT/3 carburetor to compensate for the 009 "flat spot." This helped a lot. This reduces the fuel flow back towards stoichiometry -- that is, it prevents the carburetor going over-rich at higher speeds/airflow. Every engine is different, so strongly consider getting our micro sized idle jets to really dial it in. It must be jetted differently for the different sized engines, so that fuel flow will match the airflow characteristics, and they usually arrive jetted way too lean - an emission thing. This valve closes when the key is off, preventing "Run on". On some models (the H30/31 for example) it is angled slightly towards the back of the car. If you have a significantly larger idle jet (e.g., 70 or so), John Connolly recommends going down until you can not get a good engine response with the mixture screws anymore. I find it much easier to just use a regular 13mm box-end wrench (ring sopanner), as getting the S-wrench on and off of the nut is very difficult (walls on the box (ring) end are too thick). 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. So why worry about the jets? Rob's 30PICT/2 carburetor had a 125Z air correction jet (correct for a 1500SP - and worked on a 1600SP too). Nomenclature 55 idle, 127.5 main. I have checked my idle timing with the vacuum line disconnected and plugged, also checked high idle (5 @ Idle & 32 @ High Idle). Golf Mk1 > Volkswagen Workshop Manuals > Power unit > 34 PICT, Keihin carburettor and ignition system > Mixture preparation carb. Ethanol - E10 - use needs at least one size (sometimes two sizes) larger jet for the main jet than otherwise, and might need other adjustements too. You can also get detonation (pinging/knocking) if the engine gets too hot. The optimal stiochiometric (balanced) ratio is 14.5:1 -- that is, 14.5 parts air to one part fuel. 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. . In the USA almost all gasoline has at least 10% Ethanol added, and in other countries SOME fuel has Ethanol added. It this case you would definitely need to reduce the main jet size to say the size 122.5 or the 120. While it is necessary to enrichen the fuel mixture when running an 009 distributor, you don't want the any richer than necessary since it will use more fuel. The back one (pilot?) 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. (You must log in or sign up to reply here. VW set up a vacuum advance distributor, and the stock jetting in a 34 pict 3 for a 100% stock engine. See details. Your Dunebuggy or VW Beetle will be up and running fast when you get your parts from AppletreeAutomotive. But engine sizes have much more variation, 1200cc to 1300cc is about 8% more, 1300cc to 1500cc is nearly 14% more, and 1500cc to 1600cc is about 7% more. 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. We ONLY charge for items that are available to be shipped in a timely or reasonably reliable timeframe. I think the original idle jet was a 50, but the replacement jet orifices (orifii?) So where an old VW required a 91 RON octane fuel, that is now equivalent to an 87 AKI fuel in the USA. Hey, use the stock jet size, which is 125 for the 34 PICT-3. For 1600cc engines, use an X130 main jet. all make a difference in how our old engines run, so you might need to experiment a little. You must do the opposite -- make the main jet a little bigger (X130 or X132.5) to stop the engine from hesitating when you accelerate. In either case, spending the time to properly jet your carburetor is a very worthwhile task. The air correction jet starts leaning the mixture to bring it back into balance, but as the rpms (airflow) rises to near the maximum for that carburettor, the air correction jet works too well, running the engine lean. So with a vacuum distributor, using a 55 idle, X130 or X132.5 main and about a 100 - 120Z air correction jet should provide good mixture for a 1776, without affecting fuel economy to badly (fuel consumption WILL be a little higher with the larger capacity though). 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 biggest problem I have with it was the fuel consumption. The standard jetting that the 30PICT/1 & 2 carburetors came with is size X122.5 or X125 main, size 55 idle, and size 125Z air correction jets. 1975 GL1000 Restored (sold) 1983 GL1100 Custom (sold . Run about 100 miles and then look at the tail pipe. 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). PLEASE NOTE: You are NOT CHARGED for out-of-stock items. Most gasoline in the USA now has at least 10% Ethanol added (E10), and in other countries, SOME fuel grades have 10% ethanol added. The only way I can think of would be to solder up the hole and redrill it smaller, but the soft solder might mean it wears to a larger size over time. -there is fuel in the 34 PICT 3 resevior. almost all the way to the top.-the idle 'cut off' solenoid clicks repeatedly when tested. Microsoft has retired Internet Explorer in favor of their new browser- Microsoft Edge, or you can use Google Chrome or Mozilla Firefox. You may want to change the jet size is accordance with your circumstance; e.g., smaller jet size at high altitude (X125 at 4000 ft.). If you do not hear this clicking sound, it's time to replace the idle cut-off valve. There is an pilot (idle) jet on all carburetors too - these are normally left at 55 for most carburetors (28, 30, H30/31 and 34 series), on any engine size (since it's only feeding the engine at small throttle settings anyway). Pilot jet cutoff valve: 3: Carburetor upper half: 15: Gasket: 27: Circlip: 4: Float needle valve: 16: Solex 28 PICT, 28 PICT-1, 30 PICT-1 and 30 PICT-2, remove the idle mixture screw and spring. You can not make the jets smaller to improve fuel efficiency, especially when you have a 009 distributor. Use a steady throttle - minimum acceleration. Do not allow cleaning solvent to come in contact with skin. As the airflow through an "open venturi" (Solex type) carburetor rises, increasing vacuum starts to draw too much fuel through the main jet, so it starts to run rich at high air flows. If it has the small main jet, then you'll get better performance and easier tune-ups if you change it to a size X125 (for 1200/1300/1500cc engines) or a size X127.5 (for 1600cc engines) and change the idle jet to a size 55. Carburetor Disassembly 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). 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. PRICES are subject to change without obligation. 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. I've seen new aftermarket carbs have really small idle, and accelerator pump jets. The only method of getting it exact is to run the car on a dynomometer with an exhaust gas analyser in the exhaust pipe. They are cheap enough. can find them - rare!). The idle jet is normally a little larger when used with the heavy bodied Type 2 and Karmann Ghias - in a Bug you usually use a 55, for a Type 2 or Karmann Ghia use a 60 or 65this gives you a little more power at low and medium speeds. All products purchased should be inspected, measured, cleaned and properly assembled prior to installation. Dave bought a Pierburg model 34PICT/3 carburetor from Aircooled.Net, and none of the jets had the sizes stamped on them. Seller pays for return postage.
