4. Visually inspect the spark plug. If it is cracked or chipped, or if
the electrodes are worn or burned, discard it and replace with a
new spark plug.
5. If re-using the spark plug, use a wire brush to clean any dirt
from around the spark plug base, then re-gap the spark plug.
6. Measure the plug gap with a spark plug gap gauge. The gap should be 0.7 - 0.8 mm (0.028 - 0.031 in)
(Fig. 30). Carefully adjust the gap if necessary.
7. Screw the spark plug back into the spark plug hole using the spark plug wrench. Do not over-tighten
spark plug. Recommended tightening of spark plug is ½ to ¾ of a turn (15 ft-lb torque/20.33 Nm) after
spark plug gasket contacts spark plug hole.
8. Reinstall the spark plug cap and maintenance cover.
0.7 - 0.8 mm
