SPARK PLUG

Recommended Spark Plugs:
The recommended spark plug has the correct heat range for
normal engine operating temperatures.
An incorrect spark plug can cause engine damage.
If the engine has been running, let it cool before servicing the
spark plug.
For good performance, the spark plug must be properly gapped
and free of deposits.
1. Disconnect the spark plug cap,
and remove any dirt from
around the spark plug area.
2. Remove the spark plug with a
13/16-inch spark plug wrench.
3. Visually inspect the spark
plug. Replace it if damaged or
badly fouled, if the sealing
washer is in poor condition,
or if the electrode is worn.
4. Measure the spark plug
electrode gap with a wire-
type feeler gauge. Correct the
gap, if necessary, by carefully
bending the side electrode.
The gap should be:
0.7 0.8 mm (0.028 0.031 in) − −
5. Install the spark plug carefully,
by hand, to avoid cross-
threading.
6. After the spark plug is seated, tighten with a 13/16-inch spark
plug wrench to compress the sealing washer.
When installing a new spark plug, tighten 1/2 turn after the spark
plug seats to compress the washer.
When reinstalling the original spark plug, tighten 1/8 1/4 turn
after the spark plug seats to compress the washer.
A loose spark plug can overheat and damage the engine.
Overtightening the spark plug can damage the threads in the
cylinder head.
7. Attach the spark plug cap to the spark plug.
