carb guys : rebuilt 4barrel carb (Rochester quadrajet) on my 454 , set everything as it says in tec sheet.
now I have 2 problems,
I have to prime it if it sits over night or to long &
you have to feather it on take off or it'll die.

acts fine other then that
whats my next step ?whats it sound like?

I'm giving it 2 more days if I can't get it right by then I'm just buying a new one.
