I have still yet to fix my moped. My 2001 tomos sprint still has no power whatsoever. I cleaned the carb thoroughly, i cleaned the air filter, i rode it without the exhaust and it has even less power without it, i clean the piston head and cylinder head, as well as the exhaust port, the spark plug isn't fouling out, the oil ratio is right, and I replaced the atf fluid with exactly how much it says it requires. After all that, there is still no noticeable change.
It is completely pointless to ride it because it can't make it up any hill around here, and it doesn't go any faster than walking in the long run right now. I'm disgusted with this moped right now. I just recently bought it. I've only put 400 km on it and it's already quitting on me. What the hell should I do? please help!
