It has good spark. I had a friend ground each plug to the frame individually while I cranked it, all produced large sparks. About the floats, it was not sticky when I had the carb apart, and appeared brand new. To me anyways, it appears someone did some rebuilding on this thing, but forgot new gaskets and how to tighten bolts. also, they've turned the fuel line nut into a 'channel-lock' size. It's susposed to be a 6-point, 5/8 if i'm thinking right. If that is the problem, I'm going to look into finding a custom intake and 4BBL carb setup, hopefully to gain what MPG I can while getting it running.
