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 metres), 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.
