Servicing the Spark Plugs

Service Interval: Every 200 hours—Check the spark
plugs.
Ensure that the air gap between the center and side
electrodes is correct before installing each spark plug.
Use a spark plug wrench for removing and installing the
spark plugs and a gapping tool/feeler gauge to check and
adjust the air gap. Install new spark plugs if necessary.
Type: Champion Premium Gold 2071, RC12YC, or
equivalent. Air Gap: 0.030 inch (0.76 mm)
Removing the Spark Plugs
1. Lower the loader arms, stop the engine, and remove
the key.
2. Pull the wires off of the spark plugs (Figure 23).

3. Clean around the spark plugs.
4. Remove both spark plugs and metal washers.
Checking the Spark Plugs
1. Look at the center of both spark plugs (Figure 24).
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 plugs.
Always replace the spark plugs when they have
a black coating, worn electrodes, an oily film,
or cracks.
