Not sure what caused the revving, air leak on the carb box maybe.
I have a bad clutch side seal also, so a rebuild is in order.
Seals, bearings, cruciform, clutch, and Iíll check the top end too.
I rigged up platform to hold the scooter, Iíll see if that makes things easier.
Iím not a good mechanic but I have the time.
