Servicing the Spark Plug
Service Interval and Specification
Check the spark plug(s) 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
plug(s) and a gapping tool/feeler gauge to check and
adjust the air gap. Install a new spark plug(s) if necessary.
Type: Champion
RCJ8Y or NGK
BPR4ES
Air Gap: 0.030 in. (.75 mm)
Removing the Spark Plug
(s)
1. Disengage the power take off (PTO), chock or block
tires, and turn the ignition key to off. Remove the key.
2. Pull the wire(s) off the spark plug(s) (Fig. 31). Now
clean around the spark plug(s) to prevent dirt from
falling into the engine and potentially causing damage.
3. Remove the spark plug(s).

Checking the Spark Plug
1. Remove spark plug.
2. Look at the center of the spark plug(s) (Fig. 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.
