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 equivalent) Air Gap:
0.030 in. (0.76 mm)
Removing the Spark Plug
1. Disengage the power take off (PTO), set the
parking brake, and turn the ignition key to
"OFF" to stop the engine. Remove the key.
2. Pull the wire(s) off the spark plug(s) (Fig. 18).
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.
