Thread: Carb leaking when engine is shut off.

    Default Carb leaking when engine is shut off.

    Hi all. I do not know the setup, please view pictures. The carb is leaking when I turn the engine off. I can see it dripping from the arm going from what I believe is the choke. What might cause the problem and what can I do to resolve it?

    I'd say that is a drip from the secondary throttle shaft.
    Is the carburetor level as fitted to the engine?
    I'd remove your flame arrestor, and look down the carb, since more than likely the float level is too high on the secondary side. Gary

    I have a Quick Fuel doing the exact same thing. Float set properly. Shut the car off and I can watch the float level drop slowly. Any Ideas?

    Your's is an internal leak, so not the same as the OPs. Primary or secondary side? Probably power valve blown. Gary

    Secondary side. No power valve, just a metering plate with jets.
