It had 1600 cylinders, with single port head and 30PICT/3 carburettor. Address2334 Edinburg Ave The H30/31 carburettor has a slightly larger throat than the 30PICT/2 you have at the moment. We have jetted thousands of Webers for Aircooled VWs… Interference, Carburettor/Distributor On the side of the carburettor body is a barrel-shaped object, a little larger a pen-cell battery, with a black wire connected to the outer end. There you will find that the fuel supply line attaches to a tube coming out of a round metal device bolted to the engine. So you set the idle speed to 850rpm or so, then use the volume screw to get the fastest idle, then reset the idle speed using the throttle arm screw. Kits are mated to a specifically designed and race proven isolated runner manifold. Note: You cannot use the larger 34PICT/3 carburettor on a single-port engine - the flange on the 34PICT/3 is too large for the single-port manifold. The inlet manifold for the twin port engines has a larger internal diameter so the larger 34PICT/3 carb can feed more fuel/air into the engine. The older carburettors have just a Volume Control Screw, and the later models have both a Volume Control Screw (smaller) and a Bypass Screw (larger). Air Cleaners; Aluminum Accessories VWD, VWDarrin splits in two on either side, you have what is called a Dual-Port On the throttle lever (back at the carburettor) there is a return spring that returns the Throttle Lever Screw (also called a Fast Idle Screw) to rest on the Stepped Cam on the left side of the carburettor. EMPI Deluxe Dual 40HPMX Kit. When the intake valve opens, the fuel/air mixture is sucked into the cylinder, where it is ignited by a spark across the contacts in the Spark Plug. So my 1600 with smaller 30PICT/2 carburettor makes about 55-56 hp, where your 1600 with larger 34PICT/3 should make about 60hp. Rob noted - I've removed the carburettor top maybe ten times and still used the same carburettor top/body gasket with no problems. Weber is the name when it comes to performance, reliability and race proven power for decades! How to Set the 34Pict/3 Carburetor on an Aircooled Volkswagen (Vw) Beetle. This valve shuts off the flow of fuel when you turn off the engine, to prevent "running on." The bottom of the carburettor EMPI Modified 30 PICT-1 12-Volt Choke Carburetor. This prevents flooding a warm engine, so it should start easily. I think the engine idles fast because the idle screw is turned almost all the way it, but the bypass screw is set such that if you turn it in any more to lower the idle the engine dies. But it also has to operate at idle and cruising speeds. These dual 48/51 EPC carburetor kits featuring short manifolds are for installation in a sedan with minimal or no cutting of your car, engine lid or velocity stacks. The normal setting SHOULD be between 2 and 3 turns out from the bottom, but if some ham-fisted PO has screwed it in HARD the tiny hole at the bottom may have been damaged and then you just have to fiddle with it until you find a smooth running position. Note: You can test the operation of the idle cutoff valve solenoid very easily. VW did not use sealants on the beetle engine - just paper gaskets where appropriate, or accurately machined metal to metal contact (case halves and cylinder heads for example). Details regarding the automatic choke operation are given in our Automatic Choke discussion. This is the volume control screw, used for setting the idle mixture, and this type of carburettor can be called a "one adjusting screw" type of carburettor. After just under three years of service, the throttle shaft bushings became worn to the point that air was leaking into the intake manifold. The air correction jet should be about size 125. The are alignment marks on the ring and canister body so you can see how much it's moved. Accelerator Pump These allow better breathing at higher revs for the racers to enjoy, but usually to the detriment of smooth running at low speeds (the engine gets "lumpy" at low rpms). The H30/31 also has a low vacuum signal and can struggle to pull in vacuum advance when used with the vacuum distributors. This is a perfect intake system... A true bolt in dual carb kit for your Type 4 based VW motor. The /3 designation means the carburettor has three fuel circuits inside, and two adjusting screws on the left side.

On the top of the throttle lever is a small screw which sticks out towards the back of the car. This article contains the step by step, detailed procedure for synchronizing dual carburetors on an aircooled VW engine. That's why those who race their VWs are always talking about dual 40mm Kadrons, progressive Webers etc. You have no items in your shopping cart. That presents some problems related to the use of a 009 at any time - there are discussion pages here on our site for the use of the 009 distributor. Vapor Lock On the bottom of the carburettor bowl on the left side is a large nut. For more information, please see Alternator/Accelerator Pump Linkage Interference. Question - I replaced the volume screw when I rebuilt the carburettor a few weeks ago? Have you checked and gapped the plugs lately? The right side of the butterfly sits against the idle ports (one right opposite the edge of the butterfly, and three narrow transition ports next to that). The H30/31 also tolerates the 009 distributor better than the 34 sized carburettor -- less likelihood of flat spots. Jets The original throttle shaft bushings are "garlock" split style bushings made of relatively soft aluminum, which wears after a short while and permits air to leak in around the throttle shaft, essentially making the carburetor useless. 30 Series Carburettors A side effect of the Solex type is that they can be set to run with just the right mixture at medium (town) speeds -- but the high speeds will then result in a leaner mixture. It takes three hands -- I use my channel lock pliers and hold the end of the cable to the throttle lever while I tighten the screw with the other hand. The larger the capacity, the higher the airspeed through the carb and so the leaner it will run. Can I use the 34PICT/3 carburettor on my '69 Beetle? Matchup This guide will show you some recommended jetting for standard air-cooled VW engine sizes. The idle jet should be a size 55, and power jet size 65. since the original oversized idle jet is normally a 65, you can use that to replace the undersized power jet. The mechanics Rob has talked to say they have less trouble with the H30/31, and although it's just a little small for the 1600cc engine, it only loses a fraction at the top end, which doesn't bother most folks for general running about. Replace the solenoid if necessary. Engine; if it continues as a single pipe from head to head, This is the Fuel Pump. These carburetors are primarily run on high performance engines. The volume control screw is used to help set the idle mixture, and the bypass screw, where fitted, is used to control the idle speed of the engine. Classic VW stock carburetors, dual and performance carburetors, carburetor rebuild kits, air cleaners, fuel injection, and fuel pumps. Rob responded -. Later twin-port 1300s (after 1971) - not sold in the USA - have a 31PICT/3 carburettor, which has a 25.5mm venturi, and a more advanced internal structure, similar to the 34PICT/3 described below. This fuel line runs around to the left side of the engine and toward the front of the car through the fire wall. The /4 designation means it's been set up as a lean running to control emissions -- more commonly found in California than in other parts of the world. … the head to provide the fuel/air mix to each intake valve. (To clarify: In the single-port design the port splits INSIDE Here's a picture of Dave's worn out bushings -. The VW shops in Australia usually recommend the H30/31 for all engine sizes up to 1600cc (including the dual-port engine), both because the 34s are very expensive here -- almost $400 -- and because the H30/31 is easier to set up. The ideal fuel/air mixture is called Stoichiometry. What this means is that you can have correct metering at some engine speeds but not at others. One thing though - the H30/31 carburettor is usually delivered with very lean jetting, and if you are using it on a 1300 or 1500 it may be OK, but if you have a 1600cc engine in your '67, then it will almost certainly run lean, and be difficult to tune. The air correction jet size is very important when using a smaller carburetor on a larger engine. On a 1600cc the main jet should be a size 127.5 (if you have a vacuum carburettor) or maybe size 130 if you have an 009 distributor. Choose... New Amp Ultra Dual HPMX carb kits with new offset manifold, combo linkage and air cleaners. If it's not working, you won't get a proper idle, and you'll get rough running at traffic speeds, too. This is the throttle lever; the cable is the accelerator cable. Rob wrote - The normal VW carburettors have just one throat (venturi). 2. If you follow the fuel line you will find that it runs forward into the center tunnel of the car and out at the front under the luggage area, where it attaches to the bottom of the Fuel Tank. If you are looking for a single or a pair of Weber carburetors we offer them by themselves to go onto your existing induction set up. The Carburettor - General Description and Discussion--, 28 Series Carburettors A float inside of the carburettor bowl opens and closes the needle valve to maintain the level of fuel in the carburettor bowl, similar to the float mechanism in your toilet. At the bottom of the carburettor is a second butterfly valve, the Throttle Valve (you can't see it, but trust me) which opens to supply air and fuel to the intake manifold and on to the engine. Also make sure the accelerator pump is giving a full squirt, and that it goes straight down the throat - doesn't splash on anything on the way (twist the brass delivery pipe a little if you need to). the carburettor down to the sides of the engine, where it attaches This is the fast idle cam, or stepped cam, and works with the choke to give a reliable idle on a cold engine. one for each intake valve, since the split occurs in the intake This assures that the engine has a high idle speed when cold (or it would stall), but the idle speed reduces to normal as the engine warm up. Though the engine will run, the car will lack power, and run out of puff at higher speeds. Just the hole size is different. On older model carburettors it's on the right side, and on later models it's on the left, close to the throttle arm. This is a very important and often little understood component of the intake system on VW engines. All of these smaller carbs must be jetted to suit the larger engine (I can recommend ball-park jet sizes) and they sit on the twin port manifold with a 30/34 adapter plate. The Pierburg 34PICT/3 Carburettor, Adjustment of "Single-Screw" Carburettors It might provide you with an extra hp or two, but not much though as it still has to pull that inlet mixture through the same (smaller) diameter inlet manifold. So the 34 copes with this by using 3 fuel circuits - idle, low speed and main. Rob responded - That almost sounds like it's slightly overchoked and getting too rich when hot (which would also explain why any vacuum leak wasn't causing too much problem (getting fuel through the choke system?). This is a replacement Filter Element for Bugpack's 1509-10 Mini Air Cleaner that fits Stock VW Bug Carburetors. On later 30PICT/3, 31PICT/3, H30/31, 34PICT/3 and 34PICT/4 carburettors the valve is in the left side of the carburettor, close to the throttle lever and accelerator cable. This Deluxe kit comes complete with offset manifolds that have plenty of material for extra porting. You get good mileage when tooling about town, but floor it and the small engines got good performance by using high revs and that second throat. The development of the 30/31 carburettors is interesting... the 30PICT series has a 24mm throat, and it's final development was the 30PICT/3 used in the 1970 1600 single-port engine (in the USA). 1 x Carb … The rebuilt German carburetor from Keith Doncaster does not have this interference problem. The 28 series carburettor is really too small for the 1600cc engine. Stepped cam which holds a fast idle when the choke is operating. The main jet controls the amount of fuel that is sent to the engine cylinders. These have two throats, a smaller one for idling and gentle cruising about town, and a larger throat which only opens when you step on the gas. Superb carbs with the range of high quality carburettors, manifolds and rebuild kits for the Volkswagen T1 Beetle at JK. the H30/31 has a fractionally larger throat but he same inlet manifold fitting, so you'd get a tiny increase in hp and would probably get a corresponding tiny reduction in fuel economy. Empi HPMX carb kits are the best way to convert your VW engine to dual carbs without the hassle of mixing and matching parts to make a kit. Kits include a pair of Empi... Empi has released this specifically jetted and prepared "D" carb kit for your type 1 engine. And the fractional LEAN hesitation would be part of the cause too. As you said in one of your notes, if the throttle valve is not seating properly (i.e., 0.004 inch open) it will interfere greatly with the normal IDLE flow -- i.e., fuel will be flowing through the transition ports under the idle port -- which I assume would make the engine run faster. Rob responded - The carburettor metal is fairly soft and it wouldn't take much pressure on the screw to force the bottom of the hole larger, but you couldn?t see it with a flashlight down that tiny hole anyway. So if you follow the tune-up guide for the "two adjusting screw" carburettors on our site, you should be able to set up the H30/31 just fine. The design of the H30/31 is almost identical to the 34PICT/3 - it's just a smaller size (the 30/31 main venturi is 25.5mm, the 34 has a 26mm venturi). Miscellaneous Topics Related to Carburettor Tuning, Carburetor Overhaul You can adjust the amount of squirt a little -- there are small holes under the coil spring around the pump operating arm (right side) so you can move the split pin. The ultimate in VW Dual Carb kits is here. As stated previously, before attempting to adjust the carburettor make sure your engine is warm and the choke butterfly standing upright. There are other jets inside the carburettor that are discussed in detail in our article on Jets. VW engines are notoriously under carbureted by nature of the original design. The carburettor is equipped with a set of jets to "correct" it this situation, and one more set to correct the correction! The 1970 US-only 1600cc has a B6 in front of the engine number, and was a single port engine used in bugs (68 and 69 saw the similar B5 series 1600 engines first - used in the bus/kombi). Touch the wire back onto the connector, and you should hear a clicking sound as the valve inside moves. Adjustment of "Double-Screw" Carburettors Volume screw which adjusts the idle mixture. Now you can bolt on the... Weber is the name when it comes to performance, reliability and race proven power for decades! Kit Picture Make/ Model/Year Engine Type Kit # Note Qty Model Carburetor Manifold Adapter Linkage Kit Air Filter Carb Base Gasket Adaptor Gasket Kit; T-1 & T-2 52-66: 1300, 1600 … There is a brass locating "pin" in the body (actually part of a signal system for the choke I think) which makes it easy to line the gasket up again. Interference There may be one or more Fuel Filters in this line (see our Fuel Filter discussion). The correct idle speed is important with the 34PICT/3 carburetor, which is more complicated than the … The 28PCI, 28 PICT, 28PICT/1, 30PICT/1, and 30PICT/2 all have one adjusting screw in the left side of the carburettor (the Volume screw) and an idle speed screw on the throttle arm. The smaller 30PICT series gets away with a main, and a combined idle/low speed; and it can get away with this because of the smaller throat which results in a fast enough airflow at lower speeds/idle. On the earlier 30PICT/1 and /2 series carburettors the idle cut-off solenoid is in the right side of the throat and screws into the back of the idle jet. Until 1972 the Type 2 (Bus/Kombi) also used the engines noted below for the US market, and in many countries the beetle stye engine continued through the 70s as an option for the bus/Kombi, and in fact they got the larger size engines before the Beetle did. The carburetor on a standard VW Beetle engine is located almost directly in the center of the visible part of the engine when the deck lid is opened. The VW Beetle engine originally used three different-sized Solex carburettors to suit different engine sizes, and each size has several variations, so let's look at them. There is no bypass screw on the 30PICT/2 carburettor. VW Carb Tech 103: How to Synchronize Dual Carburetors. This new complete kit for your Type 3 based VW motor comes complete with everything you need including all gaskets, hardware and fuel line. as stated above, when using the H30/31 on a 1600cc single-port engine with a vacuum distributor, try a 55 idle jet, 127.5 main jet and 125 or 130 air correction jet. Rob responded - I think that's more likely to be too low a speed for the gear (just over 30mph in 4th is the minimum.) KIPA Carburetor For VW Beetles Super Beetles 1971-1979 Dual Port 1600cc Engine 12V Electric C… What does the bypass screw do? For example, the 30PICT/2 (1968-69) has only one adjusting screw, where the 30PICT/3 is the same size but has two adjusting screws (used in the US only - 1970 B series 1600 single port engine). These kits are designed with the performance... California Prop 65 Warning: Cancer and Reproductive Harm -. Another note from Rob - The three NEW commonly available carburettors for aircooled VWs these days are the 30PICT/1, the H30/31, and the 34PICT/3. The first dual port 1600s came in 1971, and have a double letter in front of the engine number, AF or AD for that year. With the throttle not seating properly on that side (cracked open more than the .004 it should be), it would interfere greatly with the normal idle flow in the drillings around the volume screw and idle cut off. Confused? Rob responded - Well, yes, that's sort of right. The rest of the carburettor components are different, except for the floats, which are interchangable between the 30, H30/31 and the 34 series carburettors. See the jetting suggestions above. It shows a cutaway of the carburettor in good detail. Subtotal: $0.00 Category. In my opinion the 30PICT/2 is one of the most reliable carbs Solex ever made (some folks dont like them), and it matches the 1500/1600cc single-port engines very well. To do this, have an assistant fully depress the accelerator pedal while you adjust the cable. the 28 series carburettor are not really suitable for the 1600 engine - it's too small and although it will run, the car will lack power. Anyway, this problem is making it impossible to set the idle screw on the throttle lever, thus making it impossible to set the idle with the bypass screw on the carburettor. We have extensive experience with the Weber IDA, IDF, DFAV/DFEV (Progressive), and ICT. Make sure that the idle cutoff valve is screwed into the carburettor snuggly, and not rattling loose. We use these screws to "tune" the carburettor. Regular Price: $126.99 ... Air-Cooled VW … The modern H30/31 works well too - it has a 25.5mm throat. Details regarding these settings are given in the links below. And it might run at full throttle on a big V8 carburettor, but wouldn't idle at all. 34 Series Carburettors If you look closely on the left side of the carburettor you will find one or two adjusting screws.
