Purchased a non running blaster. Fixed the low compression with a fresh top end. Leak down test successful, seems to have spark but won't start. I had a couple of quick backfires but that's it. Perhaps a fuel issue? The carb seemed to be in pretty bad shape when I was cleaning and rejetting for the new pipe. I couldn't seem to get the float to hang at the correct depth (sagged down farther) no matter which way I bent the little tab. So, not sure if it is a fuel problem. I know the carb it getting gas, I loosened the screw at the bottom of the float bowl and could drain fuel from the bowl. Is there a way to quickly tell if the carb is not feeding the engine fuel? Could I remove the air intake and spray some starter fluid into the carb? Any thoughts?
