Replace a cracked, fouled, or
dirty spark plug. Do not sand blast, scrape,
or clean the electrodes because engine
damage could result from grit entering the
cylinder.
3.
Set the air gap at 0.6 to 0.7 mm (0.024 to 0.028
inch) as shown in
. Install the correctly
gapped spark plug and tighten it firmly to 23
