Lastly, you have emulsion tubes to change "where" it's rich, lean, etc. general exploded view of the 34PICT/3 Carburetor is shown in the **UPDATE*** WE ARE NO LONGER KEEPING LONG TERM BACKORDERS OPEN FOR LATER FULFILLMENT!! *** Supply-chain disruptions have hampered our ability to acquire/restock items reliably, and a lack of backorder ETA information is the frustrating "new normal" for our hobby. Rob responded - Yes, that sounds like a rich mixture. $7.99 . The selection of main gas and air correction jets is determined by venturi size. SOLEX 34 PICT 3 Carburetor Adjustment Procedures. The /4 version was used in California and had additional features to reduce emissions. Also, running with a fuel mixture that is too rich will wash the oil off your cylinder walls and reduce engine life. They might be available individually or in a set. does anyone have a link to a graphic that explains where it is on the carb? The air correction jet doesn't affect idling very much since it helps control the mixture at higher rpms, but worth a look to see if you have a fuel blockage problem in the carburetor. 55 idle, 127.5 main. Then remove a spark plug and read it (see our Spark Plug Reading Guide). It's a complex problem that faces ALL open throat style carburettors. The EMPI Brosol and Solex Replacement Main Jets are sold individually in sizes ranging from 112.5 to 170. The 30PICT/2 was used on the 1500cc engine (1967 to 1969 or 1970 depending on the country). 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 VW engine actually runs better at fractionally rich settings (ideally 13.8:1 rather than 14.5:1 according to Bob Hoover). . Use a steady throttle - minimum acceleration. Carburetor Disassembly What you are mainly looking for is the condition of the carburetor. A clean plug with a light grey/tan look means the mixture is about right. following topics related to the 30 PICT/2 and 3 and 34 PICT/3 and 4 We have had great results with these factory bench tested carburetors. The speed of the engine (RPM) when it's doing this tells you which jet you need to change. Special Instructions The venturi sizes listed below are the sizes supplied by Weber in new carburetors. That terminal on the coil is just a convenient place to obtain power to these components. Please only continue if you are prepared to be PATIENT. Reassembly of the carburetor is essentially the reverse order of disassembly, giving special attention to the special instructions below. 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). We disassemble the carburetor, and bore the venturi to 28mm for more air! 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. The extra advance helps reduce the 009 flat spot just a little. The biggest problem I have with it was the fuel consumption. Float needle valve and gasket (4 & 5) (See note below.) Then tighten further according to the chart. (Adapted from John Connolly's article on How to Jet Your Carburetor. As we learn more, we will include it here. Others might find that the 30 sized carburetor on a 1600cc engine works better with a larger X127.5 main jet. You might want to drop a pilot jet size. 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. If the jets are screw in to tight that will cause high idle. 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. It is still UNCERTAIN, but we may re-open a substantially downsized version of our store again in the Spring of 2023. The three wires could each go up to fuse #12 individually, but that would be very inconvenient. (Some of this material was adapted from John Connolly's article on How to Jet Your Carburetor.). Well, if the fuel/air mixture is too rich, the extra fuel will wash the film of oil off of your cylinders and wear out your pistons, cylinders, and rings quickly. Golf Mk1 > Volkswagen Workshop Manuals > Power unit > 34 PICT, Keihin carburettor and ignition system > Mixture preparation carb. Aircooled.Net has them, and I think Gene Berg in the US has them too. It's actually much easier to do if you remove the top of the carburetor and the float. The adjustable jet would work with any of the Solex carburetors which have the jet mounted horizontally inside the carburetor. 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). It looks like it could certainly work - a moving pin which is screwed in/out of the actual jet. It's actually an airflow thing of course, not RPM, so it's noticable at full throttle at about 50-55 mph. On some models (the H30/31 for example) it is angled slightly towards the back of the car. The Power Fuel System Dispensing Nozzle for the VW 105-1 would be 0.50 with no check ball. The power jet is usually a size 65. The emulsion tube mixes air from the air corrector jet with fuel from the main jet, and controls the mixture from the discharge nozzle at all engine speeds that the main jet is working. If the color of the deposit is tan or brown, you are running too lean and the main jet size should be increased. . On the twin port engines, it has to be used with a 30/34 adaptor, since the twin port manifold has a larger mounting flange than the single port manifold. I'd avoid Chinese stuff on eBay. 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). Another question - The car runs terrible but it runs. I also adjust my accelerator pump after getting it to idle good. I have 4-5 I've collected over the years, and the smaller ones can be re-drilled to the larger sizes. Note: Compressed air is really best if you have it. The H30/31 is the largest carburetor you can use with the normal single-port manifold. See our Accelerator Cable Adjustment Procedure. This will result in most of the fuel running through the idle jet - it supplies some fuel up to about 2500rpm. 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. 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. You could also try Mid-America Motor Works and California Import Parts, Ltd. if you have trouble finding them. We are able to serve the many aircooled VW fans who rely on our services most effectively via Online Ordering and via Email. All Solex carburetors tend to run lean at high power settings (high rpm and open throttle). Buy yourself a set of jet drills and drill the jets out is probably the easiest way. And the second issue is the presence of Ethanol (alcohol) in gasolines. The use of VW, Volkswagen and any model names and numbers is for the sole purpose of description of parts application. The idle jet should be a size 55, and power jet size 65. PRICES are subject to change without obligation. Be careful pulling it out -- it's about an inch long.

Checking and adjusting cold idle speed =>page 22-53 Throttle valve positioner 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. 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. Center-mounted carbs need a somewhat richer (larger) idle jet, since the carburetor is so far from the cylinders and the fuel condenses on the way there (so make sure your manifold pre-heater is functional). The 205L number is a Bosch number, the other one is a VW number. The 34PICT normally has a X127.5 main and a 140Z or 170 air correction jet. Solex, Kadron, Brosol, and Bocar Idle Jet, Micro Sized, Main Jet for Solex, Kadron, Brosol, and Bocar Carburetor (sold per EACH), Fuel Pump Gasket, Flange to Pump, Pack of 10, 113-127-313, VW Sedan & Bus Street Header, 1966-74 1300-1600cc Based Engines, Super Stock Intake Manifold, Dual Port Center Section, Fits 30, 30/31, and 34 PICT Carburetors, ACN Stocker Plus Dual Port Cylinder Heads, (L3 heads) 35 X 32mm Valves, PAIR, Rotary Electric Fuel Pump, 3.25 psi Low Pressure, 9mm Fuel Filter Inlet and 7.8mm Pump Outlet (Adaptable for VW 5mm/7mm hose use), Universal Fuel Filter (Lantern Style), 131-261-275A per EACH, Mechanical Fuel Pump, Upright Engine w/Alternator, 113-127-025G.

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! to start at sea level. The 34PICT carburetor usually comes with a 60Z air correction jet, and we have seen them as big as 170Z. The power jet sticks straight out to the side, and sits in a protrusion nearer the top of the carburetor - if you remove that jet you can see a drilling straight through the carburetor body to the air correction jet/emulsion tube where the the main fuel supply is delivered into the throat of the carburetor. 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). The 137.5Z air correction jet is too big -- it's letting in too much air. "Lean" means less fuel with the same amount of air, and of course "rich" is the opposite. Note: Compare the new float valve with the old one. 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. "N" on the schematic is the coil. 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. Jetting was tweaked over the years for various carbs and territories. Fillister head screw and lock washer (upper If you can't find one at about 125-130Z, try a smaller one, say 110Z. ), Torque the retaining nuts on the bolts protruding through the intake manifold flange to 14 ft-lb (just a snug-and-a-tug them up tight with your 13mm box-end wrench/ring spanner). 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. 737-240. Note: Dave found that none of the gaskets in his kit fit his carburetor. Take the car for a run at a modest speed - say 35-40mph. The air correction jet is also changeable. 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. carburetors are discussed on this page -, General Exploded View Pull it back tight (with the idle screw against the lowest step on the cam) and snug down the screw (takes three hands. to the back of the engine, in an angle) is a: g f 50 and the other: g f 50. All this indicates a good mixture and correct heat range. None of these tests are definitive - just indicative. The back one (pilot?) Pilot jet cutoff valve: 3: Carburetor upper half: 15: Gasket: 27: Circlip: 4: Float needle valve: 16: 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. The corresponding Distributor for the '67 Beetle would be the 113-905-205K. Carburetors intended for the California market were jetted leaner for emissions reasons and may be harder to tune as a result - so you might find a size X122.5 main jet and size 140Z-170Z air correction jets. Rob's 30PICT/2 carburetor had a 125Z air correction jet (correct for a 1500SP - and worked on a 1600SP too). Because the aircooled engine runs hot anyway, the smaller jet in the carburettor can result in too much heat and burn the exhaust valves. Find many great new & used options and get the best deals for Size 45 Pump Tip for Weber Dcoe Dcom Dco Carburetor Jet 76801.45 at the best online prices at eBay! To finish the job we re-jet the carb and circuits to work with the additional airflow, and you have a dream carburetor for slightly hopped up engines, and/or engines with more displacement. Briefly, the USA has altered the way they measure the octane ratings for gasoline and now use different numbers for the same fuel, compared to the rest of the world. Do not allow cleaning solvent to come in contact with skin. The effect is clearly noticeable from 3000 RPM upwards (just under 60 mph), and probably a little lower than that. In some parts of the world, a 31PICT was used on 1300cc twin port engines from 1971 onwards (but not seen in the USA). Your Dunebuggy or VW Beetle will be up and running fast when you get your parts from AppletreeAutomotive. 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. 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. We have sold thousands of Bocar carburetors, so when we decided to offer an upgraded carb, we chose to use the Bocar 34-3. 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. 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. 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. Automatic I have lowered the fuel pressure down to 2.5 psi and checked the float bowl fuel height. Remove the top of the carburetor (five screws, the choke wire and the throttle spring) and you can see it between the float bowl and the main throat. You will find the Pilot Jet Valve in the same location as on the German 30 Pict-1 Carburetor. Some of the replacement carburetors (H30/31 and 30PICT/3 maybe???) Normally, for stock daily-driver Bugs, you will find that an idle jet size of 55-60 is right for you. (See our Automatic Choke Discussion and Adjustment Procedure.). We provide the classic VW hobby with tech tips, project advice, and quality parts for VW Restoration, VW Performance and Custom Aircooled VW projects. It only works at full throttle and high RPMs ? A sooty plug means the idle jet might be a little large. Turn the Bypass Screw (the larger one) out a couple of turns, to get things started.

Useful experiment anyway. 737-144. 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. ANY SINGLE THING other than stock, Berg Semi-Hemi heads, 009 distributor, extractor exhaust, etc. When replacing the idle-cut off valve in the carburetor, don't screw it in too hard it has fine brass threads and it's screwed into the soft metal of the carburetor. Which one is which one? 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). That's how I got mine! 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. Some of you may be using this Carburetor. Another well respected and active VW carburettor rebuilder is TIM. Using a new gasket, install the carburetor on the intake manifold flange. Show Quoted Text . Most gasoline in the USA now has at least 10% Ethanol added (E10), and in other countries, SOME fuel grades have 10% ethanol added. If it's not, the float bowl will overfill through the bowl vent down the throat of the carburetor, causing the fuel/air mixture to be WAY too rich - and of course the exhaust will spew out a lot of black smoke and the engine will not run. The 30PICT/1 carburetor was used on most 1300cc engines (about 1964 to 1967, and in some countries, up to 1970). 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. For a 1600 KG with 34PICT/3 and vacuum distributor, I'd suggest a 60 or 65 idle jet (a 55 idle jet is used for the bug but the heavy bodied KGs and buses used larger idle jets), 127.5 main, 80 or 100 air correction jet (80 makes it run a little richer in the mid range) and a 65 power jet. 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. . 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). 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. Solex 34 PICT 3 VW air cooled carburettor replacement; . "Leaving it alone" is fine for a new carburettor but silly when the engines are all at least 30 years old and in different states of health. For example, a 40 IDF would need a 40 x 1.25 = 50 idle jet. 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 number which indicates the jet size is the size of the hole in the jet in milllimeters. Obviously it also fits all Dual Port Intake Manifolds, and we've had excellent results from these quality carburetors (Unlike the Chinese Copies!!!). Do you know what size high speed jet you have? 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. 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.

Following that is a listing of the parts, giving We are still processing and shipping orders from our warehouse as normal even while our site is offline. Single 40/44/45mm carburetor, venturi range 28-32mm, Typical displacement of up to 1900cc. This will have the main jet supplying the fuel, and read the plug again. 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! The smaller jets WILL NOT work with the 009 distributor. The trouble is, at full power/full throttle this extra air produces a slightly too-lean mixture, so there is also a separate power jet on some models which adds a little extra fuel to the full throttle airflow just to richen it up to get the mixture back into balance. Details. Normally, shops stock them in round sizes of "5"s, like 50, 55, 60, etc. 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. A 44 IDF would need a 55 idle jet, and a 48 IDF would need a 60 idle jet. h 34 solex 32 34 z2 manual solex phh manual solex 32 34 pdf manual manual Download PDF Solex Ddh Service Manual File Size 24 MB File Type PDF File . You also set the accelerator pump for maximum stroke when using the 009. The sizes are stamped in tiny numbers on the heads of each jet. vegas You can not make the jets smaller to improve fuel efficiency, especially when you have a 009 distributor. If it seems a little rich at higher speeds (plugs sooty after a plug read) then try the 130Z air correction jet. For 1600cc engines, use an X130 main jet. 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. 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. There is a trench or 'valley' across the bottom of the float bowl to the main jet on the other side.
