Re: Detailed Instructions?
The throttle return spring is inside the carb. If your throttle doesn't return, it's probably because of a tight fit between the throttle grip, and the handlebar. In other words the throttle handle is rubbing on the handlebars and hanging up. You may need to lightly sand down the handlebars where the throttle fits. It also might help to apply a little grease to the inside of the throttle handle.
