Assuming you are referring to a Club Car Precedent golf cart:
The governor on a Club Car Precedent golf cart can be adjusted by loosening the two screws that hold the arm in place. Once these screws are removed, the arm can be moved to the desired position and then tightened back down. It is important to note that the governor should only be adjusted by someone who is experienced with this process, as improper adjustment can lead to damage or decreased performance of the golf cart.
