Servicing the Spark Plug

Check the spark plugs after every 100 operating hours.
Make sure 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
plugs and a gapping tool/feeler gauge to check and adjust
the air gap. Install a new spark plugs if necessary.
Type: Champion RCJ8Y or equivalent
Air Gap: 0.040 in. (1.0 mm)
Removing the Spark Plugs
1. Disengage the power take off (PTO), set the parking
brake, and turn the ignition key to off. Remove the
key.
2. Pull the wires off the spark plugs (Fig. 41). Now clean
around the spark plugs to prevent dirt from falling into
the engine and potentially causing damage.

Checking the Spark Plug
1. Look at the center of the spark plugs (Fig. 42). 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 plugs. Always
replace the spark plugs when it has a black coating, worn
electrodes, an oily film, or cracks.
2. Check the gap between the center and side electrodes
(Fig. 42). Bend the side electrode (Fig. 42) if the gap is
not correct.
