At least you have someone in 40 miles... I'm in Lubbock, and the closest place is in Dallas or Austin. 300 miles at least. I'm not even sure how the moped got here in the first place. The only real help I've gotten is from a local lawnmower shop that sold me a chainsaw carb. that "should work"
You know what, It does work. Just keep after it. DON'T SELL IT
Mopeds are simple, and like everyone has told you, research.
