SPARK PLUG SERVICE
To service the spark plug, use plug wrench (standard accessory). Use
recommended spark plugs.
RECOMMENDED PLUG AND ELECTRODE CLEARANCE
To ensure proper engine operation, the spark plug must be properly gapped and
free of deposits.
CAUTION: If the engine has been running, the muffler will be very hot.
Be careful not to touch the muffler. Be sure to allow the
engine to cool before you touch the spark plug.
1. Remove the spark plug cap.
2. Clean any dirt from around the spark plug base.
3. Use a spark plug wrench to remove the spark plug.
4. Visually inspect the spark plug. Replace it if the insulator is cracked or
chipped.
Clean the spark plug with a wire brush if you plan to reuse it.
5. Measure the plug gap with the feeler gauge. Correct as necessary by carefully bending the side electrode
(Fig.29).
6. Check that the spark plug washer is in good condition. If it is not, thread the spark plug in by hand to prevent
cross threading.
7. After the spark plug is seated, tighten with a spark plug wrench to compress the washer. If you are installing a
new spark plug, tighten the spark plug 1/2 turn after it seats to compress the washer. If you are reinstalling a
used spark plug, tighten 1/8–1/4 turn after the spark plug seats to compress the washer.
NOTE: The spark plug must be securely tightened. An improperly tightened spark plug can become very
hot and could damage the engine. Never use spark plugs which have an improper heat range. Use
only the recommended spark plugs or equivalent.
