Carb leaking when engine is shut off.

[Mowes]

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.

I have the Quick Fuel 34-4 billet metering block on a 700 cfm 4150 and just discovered mine is leaking out of idle passage and draining the primary bowl after shut off. I thought it was leaking past the check needle in booster circuit. Nope. I need to know why this metering block is failure is happening. No vacuum ports on this block.
