4. Inspect the air filter to see if you can clean it or if it should be
discarded. Discard if it is too dirty and replace with a new filter.
a. Clean dirty air filter with warm water and mild soap or a non-
flammable solvent. Replace the water as necessary, until the
water is no longer dirty. Do not use a flammable solvent to
clean the foam filter. The solvent may dissolve or clog the
filter. Dispose of the oil contaminated water in accordance
with your local by-laws.
b. Allow air filter to dry.
c. Dip the filter into clean engine oil and squeeze out excess.
The engine may produce smoke when started for the first time
after the filter is replaced. This is excess oil from the filter and
the effect is temporary.
5. Reinstall the filter into the housing and secure in place.
6. Install the air filter assembly onto the carburetor and secure with
screw.

CARBURETOR ADJUSTMENT

Never make adjustments to the carburetor. The carburetor was set at
the factory to operate efficiently under most conditions. Only a qualified
service technician should adjust the carburetor if it is required.
MODIFYING THE CARBURETOR FOR HIGH ALTITUDES
At high altitude, the standard air-fuel mixture is too rich, causing
increased fuel consumption and decreased performance. A rich
mixture will also foul the spark plug and cause hard starting.
A qualified technician can improve high altitude performance with
certain modifications. Have your carburetor modified if the engine will
routinely be operated at altitudes above 5,000 ft (1,524 m). Even with
carburetor modification, engine power will decrease about 3.5% for
each 1,000 ft (305 m) increase in altitude. The effect of altitude on
engine power will be greater than this is if no modification is made.
