Inspecting and Replacing
the Spark Plug
Use a Champion RJ-19LM or equivalent spark plug.
Check and gap the spark annually, 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).

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