13.2 Carburettor Modifications for High Altitude Operation
At high altitude, the standard carburettor 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 carburettor. If you
always operate your engine at altitudes above 5,000 feet (1,500 meters), have authorized
servicing dealer perform this carburettor modification. This engine, when operated at high
altitude with the carburettor modifications for high altitude use, will meet each emission
standard throughout its useful life.
Even with carburettor modification, engine horsepower will decrease about 3.5% for each 1,000
feet (300 meters) increase in altitude. The effect of altitude on horsepower will be greater than
this if no carburettor modification is made
NOTICE
When the carburettor 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 (1,500 meters) with a
modified carburettor may cause the engine to overheat and result in serious engine damage.
For use at low altitudes, have an authorized servicing dealer return the carburettor to original
factory specifications
