Carburetor Modification for High Altitude Operation
At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will decrease, and fuel consu
-
mption 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.
Even with carburetor modification, engine horsepower will decrease about 3.5% for each 1,000-foot (300-meter)
increase in altitude. The effect of altitude on horsepower will be greater than this if no carburetor modification is
made.
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 feet (1,500meters) with a modified carburetor may cause the engine
to overheat and result in serious engine damage. For use at low altitudes, have your servicing dealer return the
carburetor to original factory specifications.

engine. You may order them from your engine dealer.
