For good performance, the spark plug must be properly gapped and free of deposits.
⚫
Disconnect the spark plug cap and remove any dirt from around the spark plug area.
⚫
Remove the spark plug with a spark plug wrench.
⚫
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.
