Spark Plug: Testing and Inspection
Cleaning the
spark plugs is not a recommended practice. If you cannot replace the spark plugs use the following procedure:
- Before cleaning, inspect the
spark plug insulators and electrodes for indications of oil fouling, rich fuel mixture, or burns. Replace if damaged.
- Clean the
spark plugs with a wire brush.
