AIR CLEANER

A dirty air cleaner will restrict air flow to the carburetor, reducing
engine performance. If you operate the engine in very dusty areas,
clean the air filter more often than specified in the MAINTENANCE
SCHEDULE.
Operating the engine without an air filter, or with a damaged air
filter, will allow dirt to enter the engine, causing rapid engine wear.
This type of damage is not covered by the Distributor's Limited
Warranty.

Inspection

Remove the air cleaner cover and inspect the filter element. Clean
or replace a dirty filter element. Always replace a damaged filter
element.

Cleaning

1. Clean the filter element in warm soapy water, rinse, and allow to
dry thoroughly. Or clean in non-flammable solvent and allow to
dry.
2. Dip the filter element in clean engine oil, then squeeze out all
excess oil. The engine will smoke when started if too much oil is
left in the element.
3. Wipe dirt from the air cleaner body and cover, using a moist rag.
Be careful to prevent dirt from entering the carburetor.

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.
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 5/8-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:
0.60 0.70 mm (0.024 0.028 in) −
5. Install the spark plug carefully,
by hand, to avoid cross-
threading.
6. After the spark plug is seated, tighten with a 5/8-inch spark plug
wrench to compress the sealing washer.
7. When installing a new spark plug, tighten 1/2 turn after the spark
plug seats to compress the washer.
8. 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.
9. Attach the spark plug cap to the spark plug.
