Just got my truck back together with a rebuilt 355 and a Holley 650 using the stock pump. I have a 4.5-9psi regulator on there which is almost completely loosened and when I start the truck after about 30 seconds fuel will just start steadily dripping from the secondary boosters at idle. After you drive about 15 minutes the engine will stall unless you keep it alive with the pedal(hard to do when you shift your own gears) and its very hard to start again. Fuel also drips down the secondary throttle shaft onto the intake with the engine off. Is my carb bad or do I still have too much fuel pressure? I had assumed about 5 psi was low enough but it keeps flooding and I'm stumped
