Checking the Spark Plug
Note:
Use a gapping tool/feeler gauge to check and
adjust the gap. Install a new spark plug if necessary.
1. Look at the center of the spark plug ( Figure 39 ).
If you see light brown or gray on the insulator,
the engine is operating properly.
Important:
Never clean the spark plug.
Always replace the spark plug when it has a
black coating, worn electrodes, an oily film,
or cracks.
