Here are the manifold flange numbers which we should expect to find on a 30 Pict-1 carburetor for a USA 1966 Beetle: Here is the manifold flange number that we should expect to find on a 30 Pict-1 carburetor for a USA 1967 Beetle:VW 105-1. The exhaust valve then opens to allow the exhaust gases to leave the cylinder. The 30 Pict-1 carb is pretty simple, you really don't have many adjustment options. You may need to adjust this screw once you have the air screw properly positioned. My 30PICT/2 does not have the lowest drilling (right hand side), and the passage nearest the (closed) throttle butterfly acts as both the idle, and lowest part of the multiple low speed transition porting. Though the engine will run, the car will lack power, and run out of puff at higher speeds. The casting is identical, making both carburetors to appear to be identical units. Screw this screw completely into the carb. Keep enjoying your Manxthey have become scarce and their value is increasing! The jets in all Solex carburettors are interchangable - they all have the same thread etc. If the carb has had water in it, there will be lots. jay. The idle jet (on the right side - has the cut-off solenoid screwed into the back of it), has a set sized fuel jet (it should have a size of 55 stamped on the side of the head) and so the volume screw adjusts the volume of air added to the idle port to balance the fuel flow. This was unclear in your original message. Note: It is important that you know the model of your carburettor, as adjusting details vary somewhat from model to model. Its whatever electrical you install into it. Jay- how do we add a photo or picture to our comments?

Air Inleakage Hello, Mark The VW 47-1 was a 30 Pict-1 carburetor introduced 8/65 for a 1300cc Beetle engine to be matched with the 113-905-205K distributor. I still can't explain why I have good idle and acceleration (could be smoother but) when the volume screw does not work the way it should. jay. If the car makes a habit of this, its time to rebuild the carburettor and replace the float needle valve, which is included in most carburettor overhaul kits. So the inlet manifold itself becomes a limiting factor. There is no bypass screw on the 30PICT/2 carburettor. Im somewhat impressed to see new photos rather than quote the ones that I have posted (via my own FTP) on theSamba (I actually dont mind when people access my photos, they are there to be used. When you bolt on the carburetor..you want to snug the carb to the manifold flange but dont try to wrench it with all of your might. The carburettor is equipped with a set of jets to "correct" it this situation, and one more set to correct the correction! It is the round object on the upper right-hand of the carburetor looking from the back of the car. Thanks, Jay, for all the details and to Neva for the great pictures. Here's a picture of Dave's worn out bushings -. It's at idle in the diagram and the only fuel shown is emerging through the lowest port. 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. The carb is marked Solex 30 Pict on the side of the float bowl. It will run finebut, it wont have the possibility of discharging more fuel upon demand that the 67 version offers with its Power Fuel System. The 67 Beetle always has been our favorite year.

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). Volume screw which adjusts the idle mixture. You, Jay and the other contributors do such amazing work and Im very grateful. Back shortly. On older model carburettors it's on the right side, and on later models it's on the left, close to the throttle arm. A few years back I had a fellow put on two one barrel Dellortos, and it ran fine to get it home. See the jetting suggestions above. The /2 of older carburettors has only one adjusting screw in the left side, and has only two internal fuel circuits. That but caught me way off-guard. Wow great write up!

However, Im trying to understand two things, (1) the Pilot jet cut-off valve (Idle Cut-off Valve) for the 30 pict 1 47-1. The script on the decklid only says Volkswagen Carburetor throttle return spring. Hopefully the gasket between the carburetor base and the manifold flange comes with the carburetor. Stepped cam which holds a fast idle when the choke is operating.

This is always open (it's called a "constant venturi" carburettor), so there is a huge variation in the amount of vacuum at the venturi, depending on how open the butterfly is, and of course the engine speed. Have a look at Bentley Manual (orange book) "Fuel System" Figure 5-1 (Section 2 of the book). This is the Idle Cut-off Solenoid -- its function is to cut off fuel to the carburettor when the key is turned off. Please read my article on 1967beetle.com and follow the sequence of explanations and photos. SKP SK133003. Then came the 30PICT/2 in 1968/1969 for the 1300/1500cc engines and the 30PICT/3 for the US-only 1970 1600cc single-port engine. Turn it in slowly until it bottoms.

Is this the stamping on the drivers side of the lower flange? Doing all that will reduce the hesitation somewhat. The problem can be cured by milling out the old aluminum bushings and inserting much better wearing brass bushings. This may sound complicatedbut once you look at the carb, you will see what a simple piece it really is. Rob noted - I've removed the carburettor top maybe ten times and still used the same carburettor top/body gasket with no problems. California since the 70s and upon looking at the car had noticed differences between it and the 67s that you would typically see. 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. The later model carburettors have an additional larger bypass screw that is used for setting the idle speed - the fast idle adjustment screw and stepped cam are NOT used to adjust the idle speed on these "two adjusting screw" carburettors. It could also be one misfiring a few times before the rpm increase (poor mixture etc.). The Japanese cars used to use them a lot. Thank you for signing up! 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. Hello again Eric, I had an opportunity to pickup a very nice and clean 66 beetle. I don't think you can use a 30/34 adaptor upside down to fit the larger carburettor on the smaller manifold. If it is closing too tightly, do the following. 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).

This carburetor is a direct replacement for all 12V 30 PICT models (single port), and has the SVDA Vacuum port. I could make it a PDF download. A bit complicated and with an unknown outcome, of course. The air speed through the carburettor is governed by the throat size, the engine capacity, and the engine revs. 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. Lets us knowe-message Eric Shoemaker @: eric@1967beetle.com for information. I discovered this misstep too late in the process to reverse it. Hopefully your engine will be purring by this time. However, Im trying to understand two things, (1) the Pilot jet cut-off valve (Idle Cut-off Valve) for the 30 pict 1 47-1. I hope that you will keep 1967beetle.com informed of your findings and progress. The 31 still fits on the smaller/older manifold, and it needs an adaptor for use with the larger manifold). Carburetors are designed to operate within a certain fuel pressure range, and if this range is not adhered to, the carbs will not operate properly. Hi Jay. The accelerator pump is pulling fuel from the bowl. Hi Jay, This flapper valve wants to be set to close very loosely! One in the bottom of the fuel bowl , one under the brass jet- plug wich would be pressed into the rim drilling when the carburetor is fully assembled. Thanks again for the article.

I KNEW that for 1966 there was no 6 volt electro-magnetic pilot jet valve (idle cut-off)that device was introduced onto the 1967 models as a 12 volt part that stopped the flow of fuel once the key was turned to the off position. 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. This will allow the carb to run, although it prob. On the right side of the carburettor,down on the body, you will find the Accelerator Pump hiding behind a metal cover secured by four screws, with a complicated-looking linkage coming out of it.
