surface. If the air filter is excessively dirty replace with a
new filter. You can use pressurized air (not to exceed
30 psi) to clean the filter. Always blow the compressed
air from inside to the outside.

water. Then allow it to thoroughly air dry. Dip the foam
filter element in clean engine oil and squeeze out all
the excess before reinstalling it. The engine will smoke
when started if too much oil is left in the foam.
H. Clean the dirt from the inside of the air cleaner body
and cover. Reinstall the air filter in housing making sure
the packing is in place beneath the filter element.
Tighten the wing nut securely.

SPARK PLUG
Replace annually or every 300 hours of operation. Always
replace with the same spark plug that came in the engine
and check gap before installing. Spark plug gap is 0.030”.
Poor spark will also occur if spark plug wire does not fit
firmly on spark plug. If this happens, reform the terminal to
fit firmly on spark plug tip.
CARBON CANISTER
Designed to collect, store, and dispose of fuel vapors
created in the fuel tank/fuel system. The canister should last
the life of the unit as long as it stays dry.
