4. Measure the spark plug electrode gap with a suitable gauge. The gap should be 0.70 - 0.80 mm. Correct the gap, if necessary, by care-

fully bending the side electrode.

5. Install the spark plug carefully, by hand, to avoid cross-threading. Tighten the spark plug with a spark plug wrench.

Note: If installing a new spark plug, tighten 1/2 turn after the spark plug seats. If reinstalling the used spark plug, tighten 1/8 - 1/4 turn

after the spark plug seats.

Caution: A loose spark plug can overheat and damage the engine. Over tightening the spark plug can damage the threads in the cylinder head.
