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.
NOTICE! When the carburetor has been modified for high altitude operation, the air fuel mixture
will be too lean for low altitude use. Operation at altitudes below 5,000 ft (1,524 m) may cause
the engine to overheat and result in serious engine damage. When using this engine at low
altitudes, have a qualified technician return the carburetor to original factory specifications.

CLEANING THE SEDIMENT CUP

CAUTION! Wear latex or rubber gloves when working on the sediment cup. The cup may contain
fuel that will cause skin irritation. Prolonged and repeated exposure to fuel on skin may result in
dry, cracked skin.
1. Switch the fuel valve to the OFF position.
2. Remove the fuel sediment cup, filter and o-ring.
3. Clean the sediment cup with a non-flammable solvent or detergent and rinse. Allow to dry.
3.1 Some chemicals will damage the o-ring material. Check for compatibility or simply replace the
o-ring.
4. Reassemble the sediment cup and o-ring.
5. Switch the fuel valve to the ON position and check for leaks. Replace the o-ring if the
installation is correct, but fuel still leaks from the cup.

EMISSION CONTROL SYSTEM INFORMATION

The combustion process produces carbon monoxide, hydrocarbons, and oxides of nitrogen.
Control of these emissions is very important for personal and environmental health.
The following instructions must be followed in order to keep the emissions from your engine within
Canadian emission standards.
1. Do not remove or alter any part of the intake, fuel, or exhaust systems.
2. Do not alter or bypass the governor linkage or speed-adjusting mechanism to cause the engine
to operate outside its design specifications.
PROBLEMS THAT MAY AFFECT EMISSIONS
If you are aware of any of the following symptoms, have your engine inspected and repaired by a
qualified technician.
1. Hard starting or stalling after starting.
2. Rough idle.
3. Misfiring or backfiring under load.
4. Afterburning (backfiring)
5. Black exhaust smoke or high fuel consumption
