Spark Plug Cleaning and Inspection
Remove the spark plug (See Electrical System chapter).
If the plug is oily or has carbon build up on it, clean the plug using a
high flash-point solvent and a wire brush or other suitable tool.
If the spark plug electrodes are corroded or damaged, or if the
insulator is cracked, replace the plug. Use the standard spark plug
or its equivalent.

Measure the gap with a wire-type thickness gauge.
If the gap is incorrect, carefully bend the side electrode with a suitable
tool to obtain the correct gap.
