Spark Plug

Check the spark plug(s) after every 200 operating
hours. Make sure that 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 inch (0.76 mm)
Removing the Spark Plug(s)
1. Disengage the blade control switch and move
the control levers to the neutral locked position
and apply the parking brake.
2. Stop the engine, remove the key, and wait for
all moving parts to stop before leaving the
operating position.
3. Pull the wire(s) off of the spark plug(s)
(Figure 28). Clean around the spark plug(s) to
prevent dirt from falling into the engine and
potentially causing damage.
4. Remove the spark plug(s) and metal washer.
