So I'm all psyched because my car handles and stops like a dream, when suddenly I can't accelerate. It starts, it idles, but put your foot into it and it just sputters and moans. Must be a float problem??? The accelerator pump seems to work because I can accelerate by pumping rapidly, but if I hold my foot in it it just dies away with the occasional sputer and backfire. Help! BTW, this is with the 1101 and a duraspark. Used to run great.
