The recommended spark plug has the correct heat range for
normal engine operating temperatures.
An incorrect spark plug can cause engine damage.
For good performance, the spark plug must be properly gapped
and free of deposits.
Disconnect the spark plug cap,
and remove any dirt from
around the spark plug area.
Remove the spark plug with a
13/16-inch spark plug wrench.
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.
The gap should be:
0.70
0.80 mm (0.028 0.031 in)
Measure the spark plug
electrode gap with a wire-
type feeler gauge. Correct the
gap, if necessary, by carefully
bending the side electrode.
Install the spark plug carefully,
by hand, to avoid cross-
threading.
When reinstalling the original spark plug, tighten 1/8 1/4 turn
after the spark plug seats to compress the washer.
When installing a new spark plug, tighten 1/2 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.
Attach the spark plug cap to the spark plug.
Move the fuel valve to the OFF position, then remove the fuel
sediment cup and O-ring.
Place the O-ring in the fuel valve, and install the sediment cup.
Tighten the sediment cup securely.
Move the fuel valve to the ON position, and check for leaks.
Replace the O-ring if there is any leakage.
Gasoline is highly flammable and explosive, and you
can be burned or seriously injured when handling
fuel.
Handle fuel only outdoors.
Stop engine and keep heat, sparks, and flame away.
Wipe up spills immediately.
After the spark plug is seated, tighten with a 13/16-inch spark
plug wrench to compress the sealing washer.
Wash the sediment cup in non-flammable solvent, and dry it
thoroughly.
