Ignition Timing: Adjustments

Basic setting of the Ignition timing

1 Start the engine and run it until it has reached normal working temperature.

2 Check that the idling speed is 850 ± 50 r/min. Adjust as necessary.

3 Check that the throttle switch is closed when the throttle is in the idling position and check that the switch is correctly adjusted.

4 Check that the ignition timing is 14° BTDC. Adjust as necessary.

5 Stop the engine if the ignition timing deviates by 7° or more.

6 Restart the engine, let it run at idling speed and check the ignition timing again. If it still deviates by more than 7°, refer to the instructions for checking the performance of the ignition system with knock sensor.
