IDLE SPEED
1. Warm engine to normal operating temperature. Check and adjust ignition timing (if necessary). Turn engine off. Disconnect throttle
position sensor connector and restart engine.
2. Check idle speed, (650-750rpm With transmission in Neutral and no electrical load on engine). If idle speed is not within specification, snap throttle to 2000-3000 RPM, 2 or 3 times, under no-load and then allow engine to return to idle.
3. Locate idle speed adjustment screw. See Fig. 4. Rotate idle adjusting screw clockwise to decrease idle speed and counterclockwise to increase idle speed.
4. Turn engine off. Reconnect throttle position sensor connector and restart engine. Run engine at 2000 RPM for about 2 minutes under no load, and then allow engine to return to idle. Idle speed should be as specified.
