• Spark plug must be securely tightened. An improperly tightened plug
can become very hot and possibly damage the generator.
• Never use a spark plug with an improper heat range.
• Never use a spark plug without damping resistance, or it will cause no
AC output.
4. Visually inspect the spark plug. Discard it if the insulator is cracked or
chipped. Clean spark plug with a wire brush if it is to be reused.
5. Install the spark plug carefully by hand, to avoid cross threading.
6. After a new spark plug has been seated by hand, it should be
tightened 1/2 turn with a wrench to compress its washer. If a used
plug is being reinstalled, it should only require 1/8 to 1/4 turns after
being seated.
7. Reinstall the ignition coil rubber boot on the spark plug securely.
8. Reinstall the panel.
