Note:
Due to the deep recess around the spark plug,
blowing out the cavity with compressed air is usually
the most effective method for cleaning. The spark plug
is most accessible when the blower housing is removed
for cleaning.
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.
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).
