AIR CLEANER SERVICE
A dirty air cleaner will restrict air flow to the carburetor. To prevent
carburetor malfunction, service the air cleaner regularly. Service

vents for cleaning the air clea ner element. A fire or explosion
could result.
Never run the engine without the air cleaner .
IMPORTANT
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

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.

spark plug seats to compress
the washer. When reinstalling a
used spark plug, tighten 1/8 1/4
turn after the spark plug seats
