Throttle Position Switch: Adjustments

Idle Contact Adjustment




1. Disconnect throttle valve switch connector.





2. Connect ohmmeter between terminals (29) and (30) and make sure continuity exists.
3. Adjust throttle valve switch position, with retaining screw, so that idle switch may be changed from "OFF" to "ON" when engine speed is about 850 rpm under no load.

Full Throttle Contact Adjustment
- The full throttle contact closes only when the throttle valve is positioned at full throttle (more than 70° opening of the throttle valve).
- The contact is open while the throttle valve is at any other position.

The full contact compensates for enrichment in full throttle.
