remove any dirt from around the spark plug area.
2. Remove the spark plug.
3. Inspect the spark plug for excessively worn electrodes, chips or
cracks in the insulator, or excessive deposits. Replace the spark
plug if you have any doubts about its condition.
4. Measure the electrode

0.028 - 0.031 inch (0.7 -
