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. Correct as ne-
ces sary by bending the side
electrode. The gap should be:
0.70 - 0.80 mm.
4. Check that the spark plug
washer is in good condition and
thread the spark plug in by
hand to prevent cross-thread-
ing.
5. When installing a new spark
plug, tighten 1/2 turn after the
spark plug seats to compress
the washer. When reinstalling a
used spark plug, tighten 1/8 1/4
turn after the spark plug seats
to compress the washer.
The spark plug
must be securely tightened. An improperly tightened spark plug
can become very hot and may damage the engine.

AIR CLEANER SERVICE
A dirty air cleaner will restrict air flow to the carburetor. To prevent
carburetor malfunction, service the air cleaner regularly. Service
more frequently when operating the engine in extremely dusty
areas.
Never use ga so line or low flash point sol-
vents for cleaning the air clea ner element. A fire or explosion
could result.
Never run the engine without the air cleaner.
Rapid engine wear will result.
1. Remove the wing nut (1) and
the air cleaner cover (2). Re-
move the elements and sepa-
rate them. Carefully check both
elements for holes or tears and
replace if damaged.
2. Foam element (3): Clean in
warm soapy water, rince and
allow to dry thoroughly. Or
clean in high flash-point solvent
and allow to dry. Dip the ele-
ment in clean engine oil and
squeeze out all the excess. The
engine will smoke during initial
start-up if too much oil is felt in
the foam.
3. Paper element (4): 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; brush-
ing will force dirt into the fibers. Replace the paper element if it
is excessively dirty. Clean in warm, soapy water and rinse. Dry
using compressed air blown from the inside out, or shake the el-
ement and allow it to air dry thoroughly. (Or clean in high flash
point solvent, remove immediately, and allow to dry.).
Remember to reinstall the air cleaner grommet
(5), replace the grommet if necessary.
SPARK PLUG SERVICE
RECOMMENDED SPARK PLUG: BPR5ES (NGK)
To ensure proper engine operation, the spark plug must be properly
gapped and free of deposits.
1. Remove the spark plug cap
and use the proper size spark
plug wrench (1) to remove the
spark plug.
If the engine
has been running, the muffler
will be very hot. Be careful not
to touch the muffler.
