Throttle Solenoid Adjustment
IMPORTANT! This final adjustment must be made after Throttle Solenoid Replacement. The
solenoid must be free to retract fully in order to turn OFF the High Amperage Pull
Circuit. Improper adjustment will result in solenoid failure and may damage the
electrical system.
With the engine OFF, disconnect the Clevis from the Throttle Lever.
Manually retract the Throttle Solenoid by grasping the piston, just ahead of the boot, and pull to
the fully retracted position.
Note: The solenoid must retract and extend smoothly.
Have a second person rotate the Throttle Lever as far as it will go.
With the Throttle Solenoid piston fully retracted, adjust the Clevis until its hole lines up with the
Throttle Link that is attached to the fully-rotated Throttle Lever. Reconnect the Clevis to the
Throttle Link.
Tighten the Throttle Solenoid Jam Nut.
