Would you rebuild an AFB or replace it with something new? The AFB is old but was never used until about a year ago. Currently the AFB has a BAD stall on hard acceleration and is BAD cold natured. I was considering EFI but I am not interested in spending the money right now. If the AFB can be helped I'm all for it but if not I'll pick up a new Edelbrock in Indy next month.
