1 NOTICE 1
Spark plugs of the wrong size or incorrect heat range can cause
engine damage.
For good performance, the spark plug must be properly gapped and
free of deposits.
Allow the engine to cool before servicing the spark plug.
1. Disconnect the spark plug cap
and remove any dirt from
around the spark plug area.
2. Use a 13/l 6 in (21 mm) spark
plug wrench to remove the
spark plug.
3. 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.
4. Measure the plug gap with a
suitable gauge.
Correct as necessary by
carefully bending the side
electrode.
Plug gap: 0.028 - 0.031 in
(0.70 - 0.80 mm)
