About the Spark Plug

The spark plug might be defective. To determine if the spark plug is defective, remove the spark plug and inspect it. If the porcelain insulator is cracked, an electrode has been burned away or damaged, or there is heavy carbon buildup at the electrode, replace the spark plug. Alternatively, if the spark plug hasn’t been replaced in a few seasons, replace it.
