Inspecting and Replacing the
Spark Plug
Use a Champion RJ-19LM or equivalent spark plug. Check
and gap the spark yearly, and replace the plug if necessary.
1. Clean around the base of the spark plug.
2. Remove the spark plug.
3. Examine the spark plug and replace it if it is cracked,
fouled, dirty, or if the electrodes are worn.
Important: Do not clean the electrodes because
grit could enter the cylinder and damage the
engine.
4. Set the gap between the electrodes on the spark plug at
0.030 inch (0.76 mm) (Figure 53).

5. Install the spark plug by hand and then torque it to 15
ft-lb (20.4 N·m).
Note: If you do not have a torque wrench, tighten
the plug firmly.
Adjusting the Discharge Chute

position or does not unlock so that you can move it to
another position, adjust the discharge chute latch.
1. Remove the fastener on the gear cover (Figure 54), lift
the front of the cover up, and slide it back and out of
the way.
