So after some light restoration of my sons ty 80 I've bolted it all back together , gone to start it and the revs are sky high , all the setting are correct , it seems like it may have anoticed air leak or something of that description. It doesn't seem to matter what I do to the carb it does not seem to make much of a difference, the annoying thing is I didn't touch the engine or carb all I did to the bike was a light cosmetic clean up can anyone help please ?
