Spark Plug: Adjustments

Spark Plug

ADJUSTMENT

Clean the spark plugs using a wire brush.
Clean and remove the carbon or oxide deposits.
But do not wear away ceramic insulator at this time.
If deposits are too stubborn, replace the spark plugs.

NOTE:  Do not use a plug cleaner because the spark plugs are applied with iridium tip.
