6.
Clean the filter elements if they are to be reused.
Paper filter element: Tap the filter element several times on a
hard surface to remove dirt, or blow compressed air [not
exceeding 207 kPa (2.1 kgf/cm , 30 psi)] through the filter
element from the air cleaner case side.
Never try to brush off dirt; brushing will force dirt into the fibers.
Replace the paper filter element if it is excessively dirty.
Foam filter element: Clean in warm soapy water, rinse, and
allow to dry thoroughly. Or clean in non-flammable solvent and
allow to dry. 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 foam.

Wipe dirt from the inside of the air cleaner body and cover,
using a moist rag. Be careful to prevent dirt from entering the air
chamber that leads to the carburetor.
8.
Place the foam filter element over the paper filter element, and
reinstall the assembled filter element. Be sure the packing is in
place beneath the filter element. Tighten the wing nut securely.

SPARK PLUG
Recommended Spark Plug:
The recommended spark plug has the correct heat range for
normal engine operating temperatures.
Incorrect spark plugs can cause engine damage.
If the engine has been running, let it cool before servicing the
spark plugs.
For good performance, the spark plugs must be properly gapped
and free of deposits.
1.
Disconnect the spark plug caps, and remove any dirt from
around the spark plug area.
2.
Remove the spark plugs with a 5/8-inch spark plug wrench.
SPARK PLUG CAP
3.
Inspect the spark plugs. Replace
them if damaged, badly fouled,
if the sealing washer is in poor
condition, or if the electrode is
worn.
4.
Measure the spark plug
electrode gaps 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 5/8-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 caps to the spark plugs.
