Spark plug service
WARNING! If the engine has been running, the exhaust will be very hot. Be careful not to touch the exhaust.
To ensure proper engine operation, the spark plug must be properly gapped
and free of deposits.
1. Remove the spark plug.
2. Visually inspect the spark plug. Discard it 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 gauge. The gap should be 0.7-
0.8mm (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.
5. After the spark plug is seated, tighten with a spark plug wrench to compress the washer.
NOTE! If installing a new spark plug, tighten 1/2 turn after the spark plug seats to compress the washer. If re-
installing a used spark plug, tighten 1/2-1/4 turn after the spark plug seats to compress the washer.
