And I have the by pass air cut off valve (12V thing) on the left side (as same as on the 30 PICT-3, which I have seen on pictures in books, but the by pass air cut of valve were always shown on the right side). Carburetor model numbers can usually be seen stamped on the side of fuel bowl. It would be interesting to try using one an adjustable main jet, but there are some dangers too ? Then remove a spark plug and read it (see our Spark Plug Reading Guide). Solex 34 PCI jets - data all cars (pdf 172 Kb 6 pages) Weber 40 DCOE 19 and Solex 40 DDH jets for 1200 TT (pdf 8 Kb 2 pages) Weber 40 DCOE and Solex 45 DDH jets for 1300 TT (pdf 8 Kb 2 pages) Credits by broos. Basically, the emulsion tube changes the diameter and location of small holes in it's body. I also adjust my accelerator pump after getting it to idle good. 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. Stock jetting in this VW 34 Pict 3 carburetor is a 55 idle jet and a 127.5 main jet. 81. Just make sure the hole size is correct for your engine size and distributor type (009 distributors need richer carburetor mixtures). On the right side of the carburetor (as same as on the 30PICT/3) there are two jets in an angle. Main jet = 132.5. Manufacturer: Classic. This jet helps mix the fuel when the throttle butterfly is part way open, and so if you make it too big, it will let in too much air, and the engine will hesitate because of that. Most carburetors come out of the box with a 55-60 idle jet. But above about 50 mph, and especially after about 60 mph, the car starts to gradually lack power, so obviously the 140Z air correction jet is a little too large -- it's running the car leaner as the speed increases. 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.

The 205L number is a Bosch number, the other one is a VW number. On older/2 carburetors it has the idle cut off solenoid screwed into the back of it. The power jet only works at higher throttle positions and higher rpms. The 30/31 is a slightly different carb, so your numbers may vary. In the 34 PICT-3, in common with all carburetors, air and gasoline are drawn in by vacuum created by the pistons descending in the cylinders. The 30PICT/3 and the H30/31 carburetors came with size X112 main (super lean), size 65 idle, and size 125Z air correction jets, which made them very difficult to tune. The optimal stiochiometric (balanced) ratio is 14.5:1 -- that is, 14.5 parts air to one part fuel. Once you have those two sorted, then try a faster run and from 60 try flooring the throttle - if you get a good smooth response the air correction jet should be OK, but if it tends to stumble a little or feel breathless, then either the main jet is a little small or the air correction jet is a little large. Most gasoline in the USA now has at least 10% Ethanol added (E10), and in other countries, SOME fuel grades have 10% ethanol added. 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. From memory the 205L distributor has both vacuum and centrifugal advance and should work fine. 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. FAQs Ask a Question. 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. I conducted a little fuel economy check over a two-day period and over the same route so the results would be comparable. FREE Shipping. 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). 34 PICT 3 Idle Jet; 34 PICT 4 Idle Jet; Jet Size G55. That means that the jetting requirement for any VW using ethanol-added gasoline/petrol is different to those using straight hydrocarbon gasoline/petrol. 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. Take the car for a run at a modest speed - say 35-40mph. They are cheap enough. This Part Fits: Beetle, Karmann Ghia, Baywindow, Splitscreen, Trekker, Buggy. Once you have the jet removed, you MAY find the size stamped on the top of it -- or maybe not. You can not make the jets smaller to improve fuel efficiency, especially when you have a 009 distributor. "N" on the schematic is the coil. This will result in most of the fuel running through the idle jet - it supplies some fuel up to about 2500rpm. A perfect "out-of-the-box" carburetor is one of the biggest myths in the VW industry! The main jet provides fuel from about 1500 rpm right up to maximum rpm. 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. $10.84 $ 10. The smaller jets WILL NOT work with the 009 distributor. Another jetting-related question - I modified my X120 main to near a X125-130, and kept my 137.5Z air correction jets. Depth: 25mm. 4.5 out of 5 stars 10. 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. Another question - The car runs terrible but it runs. Normally, shops stock them in round sizes of "5"s, like 50, 55, 60, etc. It should not need to be bigger than that with a vacuum distributor (009 distributors need richer mixtures). Once again, try the conservative approach first, then get richer only if you have to. It only works at full throttle and high RPMs ? Unscrew this bolt and look at it -- if there is a jet screwed into the bolt (older models), you can deal with it in hand, so to speak. Also check that the valve hasn't worked loose in the carburetor -- they do sometimes, and then work only intermittently. The larger 34PICT carburetor should have the larger X127.5 main jet, and since the larger 34PICT carburetor doesn't have the extreme airflow with a 1600cc DP engine that the 30PICT carburetor does, the over-rich problem is reduced, so you use a SMALLER air correction jet - less correction is needed. to the back of the engine, in an angle) is a: g f 50 and the other: g f 50. And fuels! Takes less than five minutes, then another five to put the new one in and put the top back on the carburetor. Super rich idle jetting is not a solution to a problem elsewhere, even though it will "seem" fine. 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. They looked perfect. 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. It's possible to develop partial blockage in one or more jets. Have a look at the size stamped on it too. 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. Others might find that the 30 sized carburetor on a 1600cc engine works better with a larger X127.5 main jet. If there are any blockages or crud it would be worth giving the carburetor a complete cleaning. I haven't run enough through the tank to get a real idea about consumption yet, but since I don't notice any huge difference in performance I'll probably be going back to the X125 soon. Availability: Unit of Measure: Each. An altitude of 5000 feet is roughly equivalent to a one size main jet difference. 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. 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. 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. To be honest I have never messed with the stop or curve in an 009. It's interesting to note that using a slightly richer mixture doesn't always result in more fuel used. If your solex 34 pict 3 starts and runs fine when cold. The most common power jet size on all Solex carburettor versions is 65 (except for the H30/31 which usually has a smaller power jet - around 47.5). Note: The air correction jet size is very important when using a smaller carburetor on a larger engine (e.g., a 30PICT on a 1600cc DP engine). Could you help me with the jetting? You can also get detonation (pinging/knocking) if the engine gets too hot. Sounds like a good starting point! Try the X125 main before you try the X127.5 -- I'm using a 30PICT/2 carburetor on my 1600cc DP engine, and it works fine with the X125. All suggestions here are just that - suggestions. The 34PICT normally has a X127.5 main and a 140Z or 170 air correction jet. If it's working, you'll hear a clicking sound as the relay pulls in. 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. 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. 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. You can buy different size jets for the 30/31 carb but you may want to put it together and see how it runs first. If you do not hear this clicking sound, it's time to replace the idle cut-off valve. 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. 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). 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). But engines do differ a little, and the sizes above are "ball park" figures rather than definitive. Reach through the jet plug hole (main jet cover plug (14) was removed previously) with a screwdriver and remove the main jet (17). Another - You mentioned a bigger jet -- are they available? Only 14 left in stock - order soon. "Lean" means less fuel with the same amount of air, and of course "rich" is the opposite. 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. Soot will indicate the main jet is a little too large. ). All the plugs look the same -- black and fluffy, telling me a rich condition. Aircooled.Net has them, and I think Gene Berg in the US has them too. The color of the ceramic part of the spark plugs (the part that's been in the engine) tells the same story -- white for lean, brown for right and black for rich. If that's the case you need to make sure the idle cut-off solenoid is working (a nice click when you touch the wire on the connector) and that the idle jet (which it screws into) is not blocked. Regarding fuel consumption as a function of jet size -- The 1600cc Beetle should get about 10-12km/l (24-28mpg). I'd go for a 130 main. all make a difference in how our old engines run, so you might need to experiment a little. "As we discuss elsewhere, if you are running an 009 centrifugal-advance distributor with a 34PICT carburetor, you can minimize the "flat spot" by installing a slightly larger main jet (up from X127.5 to X130 or X132.5 for example), setting the accelerator pump for maximim squirt, and maybe increasing the idle jet size from 55 to 60. The subsequent 34 PICT-3 then gained a fuel cutoff solenoid, which necessitated relocating the air bypass screw. 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. Thanks Sent from my SM-G930F using Tapatalk low_light_craig, Jun 9, 2017 #1. snotty. The power jet is needed to correct a tendency for the air correction jet to work TOO well at max airflow - it leans the mixture off too much and the power jet corrects this. In either case, spending the time to properly jet your carburetor is a very worthwhile task. There is enough variation in fuel types, wear and tear on engine and carburetor, altitude and so on that you might need to experiment a little. 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. The soldering and drilling of the Jets can apply to any carburetor! (The jets are made in 2.5 increments, so it goes X127.5, X130, X132.5, X135 etc. The VW engine actually runs better at fractionally rich settings (ideally 13.8:1 rather than 14.5:1 according to Bob Hoover). No blue fumes, so the piston rings are well installed. 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." Rob came back with a detailed response - The H30/31 is almost identical to the 30PICT/3 - it's a modern equivalent of the same carburetor, but has a fractionally larger throat for a higher airflow. 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. It worked quite well, although the idle wasn't very accurate. Just start off with a larger than normal size (150 maybe) and use the screw to increase/decrease the actual hole size. I don't think you'd honestly notice the difference. Originally Posted by wifesbug. Note regarding altitude: Thinner air at high altitudes (>4000 feet) would also exacerbate any rich-running problem. The 30PICT/1 carburetor was used on most 1300cc engines (about 1964 to 1967, and in some countries, up to 1970). 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). The main jet is accessed by removing the big brass bolt on the left side of the PICT carburetor, right at the bottom of the carburetor bowl. On the H30/31 carburetor, there are two brass jets on the right side (right is right of car). If you can't find one at about 125-130Z, try a smaller one, say 110Z. 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. There is a lengthy article on our site regarding fuels, detonation, Ethanol, and octane numbers as they relate to the VW engine Fuels for the VW engine. I've used this particular carburetor with a 1600cc dual port engine and it works fine with the same main jet, but seems to like a fractionally larger X130 air correction jet (it runs a little rich with the X125 air correction jet). 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. 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. Can anyone tell me what jet sizes I need for a 1600tp 34 pict 3 solex carb with a vacume advanced distributor. 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. If the problem occurs at higher RPM (2500-4000), then you need to richen up your main jet. 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. 34 PICT Carburetor Combination. You may have to get creative about how you attach so many wires to the single terminal on the coil. With the larger main jet, you might also need to consider a size 50 idle jet in lieu of the normal 55. Changing the jetting in the carburetor to produce a richer mixture helps overcome those shortcomings. Assuming a vacuum distributor, the 34PICT/3 carburetor is usually jetted with a X127.5 main jet, and 100Z -120Z air correction jet. Idle jets are available in small increments. What you are mainly looking for is the condition of the carburetor. Some of the replacement carburetors (H30/31 and 30PICT/3 maybe???) And the second issue is the presence of Ethanol (alcohol) in gasolines. Ethanol contains USED oxygen which canoot be burnt again, so adding ethanol to gasoline/petrol, reduces the amount of energy per litre/gallon. up enough to allow the linkage to clear the alternator . Sold by JGCParts and ships from Amazon Fulfillment. This will tell you if it's running rich or lean at speed and then you can set the air correction jet accordingly (smaller air correction means richer mixture - is delivers air so it works the opposite to a main jet. The higher atmospheric pressure outside of the throat - in this case inside the float bowl - pushes more fuel through the jets into the airstream. 30 PICT 1 Main Jet Configuration. The air correction jet has to be the right size for the same reason. (Some of this material was adapted from John Connolly's article on How to Jet Your Carburetor.). 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. That terminal on the coil is just a convenient place to obtain power to these components. The biggest problem I have with it was the fuel consumption. PICT carbs (34PICT) RPR 34 PICT-3 Carb (12 volt electric choke) RPR 34 PICT-3 Carb (12 volt electric choke) 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. The effect is clearly noticeable from 3000 RPM upwards (just under 60 mph), and probably a little lower than that. A Volkswagen friend in England recently e-messaged me about a situation with his carburetor. A clean plug with a light grey/tan look means the mixture is about right. The air correction jet must be SMALLER to enrichen the mixture. A 44 IDF would need a 55 idle jet, and a 48 IDF would need a 60 idle jet. For information -- the 1200cc engines originally came with a 28 PCI or 28 PICT carburetor, both of which have a 22mm throat. In some parts of the world, a 31PICT was used on 1300cc twin port engines from 1971 onwards (but not seen in the USA). 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. Note the three black wires leading from the positive terminal on the coil -- one to the backup lights, one to the automatic choke, and one to the idle cut-off jet. Or should I open what I have or rob from a newer model? Ask a Question about . The idle jet is usually a size 55 (when the main jet is normally a size X125 or X127.5) but it might be a size 65 if the main jet is a X122.5 or smaller. I have 4-5 I've collected over the years, and the smaller ones can be re-drilled to the larger sizes. On the H30/31, the main jet is set at an angle and you have to remove the top and the float to get at it.

The carburettor featured here is the Solex 34 Pict 3. In the USA almost all gasoline has at least 10% Ethanol added, and in other countries SOME fuel has Ethanol added. Discussion in 'Mech Tech' started by low_light_craig, Jun 9, 2017. 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. As we learn more, we will include it here. There are a few fuels which have up to 85% ethanol in them (E85). You can find 57s, etc. So VW chose this configuration. much has changed in recent years. So if you get a "too small" jet it's easy to drill out with the right sized drill, but if you get a "too large" jet it's not so easy. 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. The three wires could each go up to fuse #12 individually, but that would be very inconvenient. 34 PICT Carburetor Combination, Automatic Choke Discussion and Adjustment Procedure. , carburetor wear, etc the Solex 34 PICT 3 Solex carb with a 30 PICT-3 in...
