My husband has a keeway ARN 125cc scooter and he has a problem with it over revving and he says it is like it is trying to get stuck into the rev mode, I would like to clean his carb out but have no idea where to find the carburetor on his scooter and we can't seem to find a manual for this? could someone help please thanks @
