Checking the Spark Plug
1. Look at the center of the spark plug(s)
(Figure 40). If you see light brown or gray on
the insulator, the engine is operating properly.
A black coating on the insulator usually means
the air cleaner is dirty.
Important: Never clean the spark
plug(s). Always replace the spark plug(s)
when it has: a black coating, worn
electrodes, an oily film, or cracks.
