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 ke>
2. Pull the wire off of the spark plug (Figure 29). Clean
around the spark plug to prevent dirt from falling
into the engine and potentially causing damage.
,
Note: Due to the deep recess around the spark
plug, blowing out the caviff with compressed air
is usually the most effective method for cleaning.
The spark plug is most accessible when the blower
housing is removed for clemcing.
Remove the spark plug and metal washer.
Checking the Spark Plug
1. Look at the center of the spark plug (Figure 30).
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.
Check the gap between the center and side electrodes
(Figure 30). Bend the side electrode (Figure 30) if
the gap is not correct.
