Carburetor Adjustment; Emission Control System Information; Problems That May Affect Emissions - Power Fist 79cc OHV Manuel D'utilisation

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 (1,500 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 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 (1,500 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.

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.
