hey pauly havnt you got a holley on her still ?
if so theres a fair chance you got crud stuck in the needle and seat .
give it a cupla light taps on the retaining screw on the front of the bowl with the handle of a screwdriver, if that doesnt clear it up take the needle and seat out and blow it out .
just make sure when you put it back in its the right hieght , just letting fuel dribble out the site plug on the side of the bowl and you should be on a winner hopefully !
holleys are prone to this drama, maybe wack a new fuel filter on too.
