Mechanical Governor Arm Adjustment Procedure
Make this adjustment whenever the governor arm is
loosened or removed from the cross shaft. See
Figure 6-26 and adjust as follows:
1. Make sure the throttle linkage is connected to the
governor arm and the throttle lever on the
carburetor.
2. Loosen the hex nut holding the governor lever to
the cross shaft.
3. Move the governor lever toward the carburetor as
far as it will move (wide open throttle) and hold in
this position.
4. Insert a nail into the hole in the cross shaft and
rotate the shaft counterclockwise as far as it will
turn. Tighten the hex nut securely and then remove
the nail.
