Maintenance (cont’d)
2.
Visually inspect the spark plug. Discard if the insulator is cracked or chipped. Clean the spark plug with a wire brush
if it is to be reused.
3.
Measure the plug gap with a feeler or gauge. The gap should be .07-.08mm (0.028-0.031 in). Correct as necessary
by bending the side electrode.
4.
Check that the spark plug washer is in good condition and thread the spark plug in by hand to prevent cross-
threading. If spark plug is damaged, replace with a new one.
5.
After the spark plug is seated, tighten with a spark plug wrench to compress the washer.
NOTE:
When installing a new spark plug, tighten ½ turn after the spark plug seats to compress the washer. When
reinstalling a used spark plug, tighten 1/8-1/4 turn after the spark plug seats to compress the washer.
Idling Adjustment
1.
Start the engine and allow it to warm up to normal operating temperature.
2.
With the engine idling, turn the pilot screw in or out to the setting that produces the highest idle rpm. Standard idling
will be 1500 ± 150 rpm.
CAUTION
The spark plug must be securely tightened. An improperly tightened spark plug can
become very hot and may damage the engine.
