Removing the Spark Plug
1. Disengage the blade control switch, move the
motion controls outward to the park position, stop
the engine, and remove the key.
2. Before removing the spark plug(s), clean the area
around the base of the plug to keep dirt and debris
out of the engine.
Pull the wire off of the spark plug(s) (Figure 31).
3. Clean around the spark plug(s) to prevent dirt
from falling into the engine and potentially causing
damage. Remove the spark plug(s) and metal washer.

Checking the Spark Plug
1. Look at the center of the spark plug (Figure 32).
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. Always
replace the spark plug when it has a black
coating, worn electrodes, an oily film, or cracks.
2. Check the gap between the center and side electrodes
(Figure 32). Bend the side electrode (Figure 32) if
the gap is not correct.
