hello, i got one venturi on the primary of my holley that is pouring out fuel pretty steady when idling and at steady throttle. what does that mean, float adjustment problems. when i push the gas and hold it, the car stumbles and makes a sucking noise intermittantly. the sound is the fuel leaking because it makes the sound at the same time as the fuel drop out of the venturi. it stumbles at the same time too. got answers for me.
