4. Use the wrench supplied in the tool kit to remove the spark plug.
5. Visually inspect the spark plug. Discard it if the insulator is cracked or
chipped.
6. Measure the plug gap with a feeler gauge.
The gap should be 0.6-0.7 mm (0.024-0.028 in). Correct as necessary by
bending the side electrode.
7. Attach the plug washer. Thread the plug in by hand to prevent
cross-threading.
8. Tighten a new spark plug l/2 turn with the wrench to compress the washer.
If you are reusing a plug, it should only take l/8-1/4 turn after the plug
seats.
CAUTION:
l
The spark plug must be securely tightened. An improperly tightened plug
can become very hot and possibly damage the generator.
l
Never use a spark plug with an improper heat range.
