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
REPLACEMENT PARTS
The emission control systems on your engine were designed, built, and certified to conform to Canadian emission
regulations. The use of genuine parts is recommended whenever maintenance is done to the engine. Genuine
replacement parts are manufactured to the same standards as the original parts. Using replacement parts that are
not of the original design and quality may impair the effectiveness of your emission control system.
It is the responsibility of the manufacturer of an aftermarket part to certify that use of the part will not result in a
failure of the engine to comply with emission regulations.
MODIFYING THE CARBURATOR 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 carburator
modified if the engine will routinely be operated at altitudes above 5,000 ft (1,500 m). Even with carburator
modification, engine horsepower will decrease about 3.5% for each 1,000 ft (300 m) increase in altitude. The effect
of altitude on horsepower will be greater than this is if no modification is made.
CAUTION! When the carburator 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
carburator to original factory specifications.
