Servicing the Spark Plug

Service Interval/Specification
Check the spark plug(s) after every 200 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 RC12YC or Champion Premium Gold
2071 (or equivalent)
Air Gap: 0.040 inch (1.02 mm)
Removing the Spark Plug
1. Disengage the PTO and set the parking brake.
2. Stop the engine and wait for all moving parts to stop
before leaving the operating position.
3. Pull the wire(s) off the spark plug(s) (Fig. 33). Now
clean around the spark plug(s) to prevent dirt from
falling into the engine and potentially causing damage.

Checking the Spark Plug
1. Look at the center of the spark plug(s) (Fig. 34). 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(s). Always
replace the spark plug(s) when it has: a black coating, worn
electrodes, an oily film, or cracks.
2. Check the gap between the center and side electrodes
(Fig. 34). Bend the side electrode if the gap is not
correct (Fig. 34).
