2Jam Nut

3Solenoid Link

4Shoulder Bolt

5Throttle Lever

6Solenoid Rod

7Throttle Solenoid Mounting Screw

Loosen jam nut, remove shoulder bolt, and remove link from throttle lever. Install link 1/2 in (13 mm) on solenoid rod. Reconnect link to shoulder bolt and throttle lever.

Push solenoid rod into idle (ener- gized) position and check for non- binding lateral movement of throttle link at throttle lever. If link binds, loosen solenoid mounting screws. Move the solenoid slightly until the link moves freely with solenoid in relaxed and energized positions. Tighten screws.

Tighten jam nut.
