Idle position switch adjusting

The throttle linkage moves a drag arm approximately 1 mm before the throttle plate starts to open. When the drag arm has been moved approximately 1 mm, a click will be heard from the idle microswitch. This indicates that the switch has opened, interrupting power to the idle speed control valve.

Although the idle position switch itself needs no adjustment, the throttle valve drag arm clearance must be set in order to not damage the idle switch upon rapid closing of the throttle.

^ To adjust switch, push throttle cable reversing lever (on transmission housing) in direction A.

• Throttle linkage to reversing lever clearance (B) should be 1 - 2 mm (0.04 - 0.08 in.)

Reversing Lever

Working at throttle housing:

• Use set screw (E) to adjust drag arm clearance (D) to idle switch housing.
