Checking the Spark Plug
Important: Do not clean the spark plug. Always
replace the spark plug when it has a black coating, worn
electrodes, an oily film, or cracks.
Note: If you see light brown or gray on the insulator, the
engine is operating properly. A black coating on the insulator
usually means that the air cleaner is dirty.
Set the gap to 0.76 mm (0.030).
