Inspect the spark plug. Replace it if the electrodes are worn, or if the insulator is

cracked or chipped.
Measure the spark plug electrode gap with a suitable gauge. The gap should be

0.028 ~ 0.031 in (0.7 ~ 0.8mm). Correct the gap, if
necessary, by carefully bending the side electrode with a
suitable tool.
Install the spark plug carefully, by hand, to avoid

cross-threading.
Install the spark plug cap on the spark plug.

NOTICE: A loose spark plug can overheat and damage the engine. Over tightening
the spark plug can damage the threads in the cylinder head.
