Would you fly this Aircraft?

Idle cutoff stops flow of fuel to the venturi/throat, but
the float valve stops the flow of fuel into the carb float
bowl.

| Don't see how the carb float valve could be leaking; the
mixture is at idle cutoff, right?

OK, so the float bowl is always filled as far as the (good) float/needle allows it to be while the mixture control is
downstream of the float needle? Actually makes sense because the float is supposed to control the head pressure against
the carb jet, and putting a cutoff in front of the float would only cause the bowl level to lower with very slight
leaning due to the reduces head pressure. One of these days I'll get to mess around with one of these engines....

Thanks Jim...

I had a commercial pilots certificate for some time before I
attended A&P school [Spartan] and I learned that I didn't
know a lot of things about aircraft engines that I think a
pilot should know.
