• Check the spark plug. Replace it if the electrodes are worn, or the insulator is cracked or
fissured.
• Measure the spark plug electrode gap with a suitable gauge. Correct the space by carefully
bending the side electrode with a suitable tool if necessary. The distance should be 0.028 ~
0.031 inch (0.7 ~ 0.8 mm).
• Insert the spark plug carefully by hand to avoid overtightening.
• Place the spark plug cap on the spark plug.
Caution: A loose spark plug can overheat and damage the engine. Tightening the spark plug too
tightly can damage the thread in the cylinder head.
