Spark Plug Check and Cleaning

Spark Plug Check And Cleaning:

1. Remove the spark plug cables.

CAUTION: When pulling the spark plug cable boot from the plug, always hold the boot, not the cable.

2. Remove the spark plugs.
3. Check for a burned-out electrode or damaged insulator. Check for even burning.
4. Remove carbon deposits with wire brush or plug cleaner. Remove sand from plug screw with compressed air.
5. Use a gap gauge to check the plug gap. Standard value: 1.22 - 1.35 mm (0.048 - 0.053 in). If the plug gap is not within the standard value range, adjust by bending the ground electrode.
