My Scooter has me scratching my head.

Have you verified there is a good strong spark? Just throwing parts at the problem isnt going to fix it. If your getting good spark, good fuel, then the next step is to check to see if the flywheel key sheered off, which throws the engine's spark out of time. And not amount of parts is going to fix the timing if the key is sheered off. Its a tiny alum key that keeps the flywheel in a precise spot on the crankshaft. Check that and report back to me. I am a professional small engine mechanic. The flywheel key is your next place to check, going by what you have done and if you have verified that you are getting a nice strong spark. Mike
