Governor adjustment
To adjust the governor:
1. Remove the fuel tank by following the procedures
described in the fuel tank section of this chapter.
2. Loosen the governor arm nut but do not remove the
nut completely.
3. Pry open the governor arm crimp with a flat head
screwdriver.
See Figure 4.47.
4. Using pliers, grab the flat section at the top of the
governor shaft and rotate it in a counter clockwise
direction as far as it can go.
5. Push the governor arm to the right (the spring should
pull it in this direction).
NOTE: Rotating the shaft counter clockwise will ensure
the governor cup is pressed all the way down on
the governor gear flyweights. Pushing on the gov

ernor arm to the right ensures the throttle is wide
open against the throttle stop.
6. Re-tighten the governor arm nut to crimp the governor arm onto the governor shaft.
7. Install the fuel tank.
8. Test run the engine in a safe area. Set the engine RPM’s to 3500 + 100.
