H.Adjust Idle Speed and Basic Timing

1. Start the engine and warm it to the operating temperature.

2. Run the engine for at least five seconds between 2000 and 3000 RPM.

3. Using a tachometer, check the idle speed. If it is not between 650 - 850 RPM, readjust it to 750 RPM using idle speed adjusting screw No. 1 (SAS1).


4. After the idle speed has been verified, adjust the basic ignition timing to 8 degrees BTDC using the Service Manual Procedure.

NOTE: This is a new basic timing specification.

Recheck the idle speed and adjust if necessary.

5. Turn off engine, disconnect tachometer, and on manual transmission vehicles only, reinstall air cleaner assembly.
