Air filter - Dual element type
1. Remove the wing nut and the air cleaner
cover. Remove the elements and separate
them. Carefully check both elements for
holes or tears and replace if damaged.
a) Foam element: Wash the element in a
solution of household detergent and
warm water, then rinse thoroughly, or
wash in PAPER nonflammable or high
flash point solvent. Allow the element to
dry thoroughly. Soak the element in clean
engine oil and squeeze out the excess oil.
The engine will smoke during initial start-
up if too much oil is left in the foam.
b) Paper element: Tap the element lightly
several times on a hard surface to remove
excess dirt, or blow compressed air
through the filter from the inside out. Never
try to brush the dirt off; brushing will force
dirt into the fibers. Replace the paper
element if it is excessively dirty.
Fuel sediment cup cleaning
Turn the fuel valve to OFF. Remove the
sediment cup and O-ring and wash in
nonflammable or high flash point solvent. Dry
them thoroughly and reinstall securely. Turn
the fuel valve ON and check for leaks.
NOTE: If any fuel is spilled, make sure the
area is dry before testing the spark plug or
starting the engine. Fuel vapor or spilled fuel
may ignite.
Spark Plug Service
Recommended spark plug: BPRGES (NGK) or
W20EPR-U (ND)
NOTE: Never use a spark plug of incorrect
heat range.
To ensure proper engine operation, the spark
plug must be properly gapped and free of
deposits.
1. Remove the spark plug cap and use a
spark plug wrench to remove the Plug.
2. Visually inspect the spark plug. Discard it if
the insulator is cracked or chipped. Clean
the spark plug with a wire brush if it is to
be reused.
3. Measure the plug gap with a feeler gauge.
The gap should be 0.7-0.8 mm (0.028-
0.031 in). Correct as necessary by bending
the side electrode.
4. Check that the spark plug washer is in
good condition and thread the
5. After the spark plug is seated, tighten
with a spark plug wrench to compress the
washer.
NOTE: When installing a new spark plug,
tighten ½ turn after the spark plug seats to
compress the washer. When reinstalling a used
spark plug, tighten
plug seats to compress the washer.
Carburetor adjustment
1. Start the engine and allow it to warm up to
normal operating temperature.

in or out to the setting that produces
the highest idle rpm. Usually the correct
setting will be found to be:
Dual element type

NOTE: Do not tighten the pilot screw against
its seat; this will damage the pilot screw or
seat.
