Hey all,

My carb is leaking very slowly from a ‘plate’ on the front of it. (see below picture)

The car had been sitting for over 20 years. It ran, but the idle was really rough and inside the carb was filthy. I took it off the car to take a look at the main jet (which I could barely see through) and to clean things up a bit.

I’ve since put the carb back on the car but it wont run now. It won’t start but will turn over. (I’m troubleshooting that and will upload a video later)

However, any input on the leak would be helpful.

Thanks!

Common issue. Back in the day we would clean it really well with carb cleaner (the non EPA approved stuff we have today) and smear a blob of JB a Weld over it. Let it set up completely before using it.

I know this doesn't answer your question but that looks like a good core to send to Volksbitz for restoration.

Your "assumed" inexperience with carbs and the fact that it has been sitting for 2 decades suggests you should just get it restored.

Funny you say that! I sent him a message earlier today. Thanks!

Thanks for the reply. I thought about that too, but because it seems too simple I thought I’d reach out.

Tim (Volkzbitz) is the man with the golden hand of carburetor rebushing and restoration. Cannot go wrong with him.

That is just a manufacturing plug. Sealing the plug won't fix the real issue. If fuel is leaking out of that plug, that means fuel is flowing down the inside of the carb. Likely the bowl is overflowing. Could be a bad float, or a stuck needle valve, or improperly set fuel level, or ...

Time to get that carb rebuilt.

Was thinking the same ^^^. Yes have Tim go through it. It will be perfect and you will have a piece of mind that it operates as it should.

Tim got back to me! What a super helpful guy!!! For those of you interested, here is his response:

Hi Kelly.

Yes, I can help you out. I ship quite a few carburetors to Canada.

Leaking gas from the throttle shaft and the plug indicates that the carburetor is flooding. This can be caused be a few things. If the float is like a solid sponge type it may have absorbed fuel causing it to sink, it should weigh about 10.5 to no more than 11 grams. Check the float valve to make sure noting is holding it open also it should have about 1.5mm total of washers under it. It looks like a newish fuel pump, this could be pushing too much pressure, these carburetors need up to 3.5 psi, much more and it can flood the carburetor.

Hope this helps, let me know if you have any questions.

By the way, keep that distributor especially if it’s a German Bosch, it’s the best match for the 34PICT-3s and the German ones are getting hard to find.

Regards
Tim
