To install the governor arm:
1. Attach the throttle linkage and return spring.

3. Rotate the governor shaft clockwise until it stops.
4. Slide the arm onto the shaft. The flat on the top of the shaft should be roughly parallel to the arm that connects

NOTE: There is a hairpin clip that keeps the governor shaft from sliding into the engine. It may be necessary to
hold the shaft while sliding the arm on to prevent the hairpin clip from "popping off" and allowing the governor
shaft to fall into the engine.
NOTE: The alignment marks from the previous section can help align the arm.
