1. Unsnap the air cleaner cover
clips, remove the air cleaner
cover, and remove the air
filter element.
2. 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.
3. Soak the air filter element in
clean engine oil and squeeze
out the excess oil. The engine
will smoke during initial

SPARK PLUG
Recommended Spark Plugs: BPR6ES (NGK)
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.
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. 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.
