Carburetor Modification for High Altitude Operation
At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will
decrease, and fuel consumption will increase. A very rich mixture will also foul the spark
plug and cause hard starting. Operation at an altitude that differs from that at which this
engine was certified, for extended periods of time, may increase emissions.
High altitude performance can be improved by specific modifications to the carburetor. If
you always operate your engine at altitudes above 5,000 feet (1,500 meters), have your
servicing dealer perform this carburetor modification. This engine, when operated at high
altitude with the carburetor modifications for high altitude use, will meet each emission
standard throughout its useful life.
