4. Inspect both air filter elements, and replace them if they are
damaged. Always replace the paper air filter element at the
scheduled interval (see page 6).
5. Clean the air filter elements if they are to be reused.
Paper air filter element: Tap the paper air filter element several times
on a hard surface to remove dirt, or blow compressed air [not
exceeding 207 kPa (2.1 kgf/cm
from the air cleaner case side. Never try to brush off dirt; brushing will
force dirt into the fibers. Replace the paper air filter element if it is
excessively dirty.
Foam air filter element: Clean in warm soapy water, rinse, and allow
to dry thoroughly. Or clean in non-flammable solvent and allow to
dry. Do not put oil on the foam air filter element.

Do not twist.
6. Wipe dirt from the inside of the air cleaner case and cover using a
moist rag. Be careful to prevent dirt from entering the air duct that
leads to the carburetor.
7. Place the foam air filter element to the air cleaner cover, then reinstall
the paper air filter element and cover to the air cleaner case.
8. Install the air cleaner cover, and tighten the two screws securely.

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.
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:
0.6–0.7 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 a used spark plug, tighten 1/8–1/4 turn after the
spark plug seats to compress the washer.
TORQUE: 12 N·m (8.7 lbf·ft, 1.2 kgf·m)
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.
