It's a 64cc polini kit on an e50.
15 Bing w/ high flow airfilter. 90 jet.
bullet exhaust
16/45 gearing.
Yeah, I've tried all sorts of different jets, it's not a jetting/carburetor issue; how could it be, when all I that was changed was the points?
The spark seems to be solid when I test it by holding the plug to ground and turning the flywheel by hand.
I've seriously tried EVERYTHING I can think of, nothing works:(
The only thing I can reason is that for some reason there must be inconsistent spark at low rpms... But why?
Any ideas?
Thanks!!
