Spark Plug Removal and Replacement
1. Use a spark plug wrench to remove the spark
plug.
2. Inspect the spark plug each time you change the
oil. The electrodes should be kept clean and free
of carbon. The presence of carbon or excess oil
will reduce proper engine performance. If
possibe, check the spark plug gap (area between
electrodes) using a wire feeler gauge.
3. Before installing spark plug, coat threads lightly
with graphite grease if possible, to ensure easy
removal next time the spark plug needs
inspection.
4. Reverse the procedure for spark plug installation.
Torque to specification. See page 54.
NOTE:
It is advisable to replace the spark plug at least
once a year to insure easy starting and good engine performance.
