Spark Plug Cleaning and Inspection
Carefully pull the plug cap from the spark plug, and re-
move the spark plug.
If the plug is oily or has carbon built up on it, clean the
plug using a high-flash point solvent and a wire brush or
other suitable tools.
If the spark plug electrodes are corroded or damaged, or
if the insulator is cracked replace the plug with a new one.
Use the standard spark plug or its equivalent.

Spark Plug Gap Inspection
Measure the gap with a wire-type thickness gauge.
If the gap is not correct, carefully bend the side electrode
with a suitable tool to obtain the correct gap.
