if the electrodes are worn, or if the
insulator is cracked or chipped.
4.Measure the spark plug electrode
gap with a suitable gauge.
Correct the gap, if necessary, by
carefully bending the side
electrode.
The gap should be:
0.7–0.8 mm (0.028–0.031 in)
5.Install the spark plug carefully, by
hand, to avoid cross-threading.

compress the washer.
If reinstalling the used spark plug, tighten 1/8–1/4 turn after the
spark plug seats.
If installing a new spark plug, tighten 1/2 turn after the spark plug
seats.
A loose spark plug can overheat and damage the engine.
Overtightening the spark plug can damage the threads in the cylinder
head.
