ok so I figured I would take carb apart Rochester for 1956 235. followed instructions and when I was removing screws on the butterfly on the base section the screw broke off. When drilling it out the drill moved ever so little. What a mess. anyway; I figure if I drill it out a little over sized I can get a little larger screw in there after I tap it out. Will the little larger screw because it is a little heavier mess up anything with the movement of the butterfly?
If I can't do this where can I get a new butterfly shaft?
Any help would make me feel better as I have called myself an idiot all weekend.
