Servicing the Spark Plug
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(s)
1. Disengage the power take off (PTO) and turn
the ignition key to off. Remove the key.
2. Pull the wire(s) off the spark plug(s) (Figure 24).
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) and metal washer.

Checking the Spark Plug
1. Look at the center of the spark plug(s)
(Figure 25). 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.
