Move the fuel valve to the OFF position, then remove the fuel
sediment cup and O-ring.
Gasoline is highly flammable and explosive, and you
can be burned or seriously injured when handling
fuel.
Stop engine and keep heat, sparks, and flame away.
Handle fuel only outdoors.
Wipe up spills immediately.
Unsnap the air cleaner cover
clips, remove the air cleaner
cover, and remove the air
filter element.
Wash the element in a
solution of household
detergent and warm water,
then rinse thoroughly, or
wash in non-flammable or
high flash point solvent.
Allow the element to dry
thoroughly.
Attach the spark plug cap to the spark plug.
A loose spark plug can overheat and damage the engine.
Overtightening the spark plug can damage the threads in the
cylinder head.
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.
Install the spark plug carefully,
by hand, to avoid cross-
threading.

The gap should be:
Measure the spark plug
electrode gap with a wire-
type feeler gauge. Correct the
gap, if necessary, by carefully
bending the side electrode.
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.
Remove the spark plug with a
13/16-inch spark plug wrench.
Disconnect the spark plug cap,
and remove any dirt from
around the spark plug area.
For good performance, the spark plug must be properly gapped
and free of deposits.
An incorrect spark plug can cause engine damage.
The recommended spark plug has the correct heat range for
normal engine operating temperatures.

Move the fuel valve to the ON position, and check for leaks.
Replace the O-ring if there is any leakage.
Soak the air filter element in
clean engine oil and squeeze
out the excess oil. The engine
will smoke during initial
startup if too much oil is left
in the element.
Reinstall the air filter element
and the cover.
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.
Place the O-ring in the fuel valve, and install the sediment cup.
Tighten the sediment cup securely.
