Spark Plug Cleaning
The plugs may be cleaned using commercially available
spark plug cleaning equipment. After cleaning, file the center electrode flat with a small point file or jewelers file before adjusting gap.
CAUTION: Never use a motorized wire wheel brush to clean the
spark plugs. Metallic deposits will remain on the spark plug insulator and will cause plug misfire.
