Default Re: GAV leaking

"With the air filter removed, and the car not running, the throat of the carb intake is pooling with fuel. I believe my GAV is fully closed so I assume the needle isn't seating fully."
The GAV needle won't cause fuel to leak out of the carb, a non sealing GAV needle will cause rich running but will not cause fuel to pool in the throat of the carb.
