I have a Regency with a M56 engine in it. The motor has been completely rebuilt, timing was set back to the factory specs, etc. The moped runs great, however, I need help with what I hope is a minor issue.
Not always, but sometimes, when I am out riding, the throttle "sticks" and I can't get the bike to idle down - it races at full throttle until the bike is turned off and I play with the throttle cable. Everything seems to be attached right, so what would cause this issue, and what can I do to fix it?
I have 2 more Regencies to rebuild, and am hoping to fix this issue before starting on the other bikes.
