I think by expensive parts he meant the carb itself. Replacing it with a 1 barrel will cost you like 300-400 for a new one or like 250 for a rebuild. Good Luck, my 1 Barrel isnt so hot either but I will have to make do for now I can't afford a new one.
Hi, I'm always curious and reading about carb stuff...maybe eventually I'll learn something. I have a spare single barrel Rochester, unknkown condition but can't see any cracks or obvious problems. PO has attached a neat little bar to thread extra jets into for high altitude I suspect. Dunno what they go for, make me an offer if you need it. This had a Man-a-fre spacer under it that was in pretty poor shape. If yours has one I'd look close at it for cracks. I can get more details on the carb next week when I'm at the shop all week.
