Assemble Governor
1. Install detent plunger, spring and pin in levers.2. Install bearings in each side of the governor housing with tooling (A).3. Install levers and shaft in governor housing. The position of the bearings can make a difference in the position of the levers. With the levers pushed against the bearings on the boss side, clearance (X) between the guide for the governor spring and levers must be approximately .135 in. (3.43 mm). With levers pushed against other side the clearance (Y) on the other side must be approximately .100 in. (2.54
