Every 100 hours—Replace the spark plug.

Ensure that the air gap between the center and side electrodes
is correct before installing the spark plug. Use a spark plug
wrench for removing and installing the spark plug and a
gapping tool or feeler gauge to check and adjust the air gap.
Install a new spark plug if necessary.

Checking the Spark Plug

Important:

Do not clean the spark plug(s). Always

replace the spark plug(s) 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 the air cleaner is dirty.

Set the gap to 0.76 mm (0.030 inch).
