4.5.3 Governor Actuator
Governor Actuator Testing: Disconnect the two actuator leads and apply 12 VDC. Replace
the actuator if the actuator arm does not move smoothly and without binding to the wide open
throttle position (rotation of approximately 35 degrees).
Governor Actuator Replacement:
NOTICE
It is beneficial to remove the air cleaner including the base for this procedure and to
place a clean rag in the "V" between the cylinders to catch any small fasteners that may
drop.
1. Mount the actuator on its bracket with the lever pointing down (approximately 8 o'clock). Do
not tighten the screws at this time.
2. Connect one end of the ball end throttle link to the mixer arm, using a washer on both
faces of the arm and one end to the actuator lever, tightening both screws to 6 in/lb-f.
3. Hold a 3/32" diameter rod (a drill bit works well) at the wide open throttle slot. Pushing the
governor actuator arm counter-clockwise to wide-open the throttle, slide the actuator in its
slots until the throttle lever just touches the rod. Tighten the two actuator mounting screws
to 6 in/lb-f.
4. When the linkage assembly is released, the throttle lever arm should rest against the low
idle screw.
5. Push the link to check that the throttle arm can open fully to the 3/32" diameter rod and
touch the low idle screw. If not, readjust the position of the actuator. The throttle should
open fully and close fully.
