  2. Prior to removing the spark plug, spray compressed air into the cylinder head opening. This will help prevent foreign material from entering the combustion chamber.
    CAUTION:

    The spark plug tubes (1) are a thin wall design. Avoid damaging the spark plug tubes. Damage to the spark plug tube can result in oil leaks.

  3. Remove the spark plug from the cylinder head using a quality thin wall socket with a rubber or foam insert.
  4. Inspect the spark plug condition.
