Removing the Spark Plug

brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
Figure 48
Checking the Spark Plug
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.
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 0.030 inches (0.75 mm).
