TECHNICAL INFORMATION
CARBURETOR MODIFICATION FOR HIGH ALTITUDE OPERATION
At high altitude, he 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 plugs 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
generator at altitudes above 1,500 meters, have your authorized THIS servicing dealer perform this carburetor
modification.
Even with carburetor modification, engine horsepower will decrease about 3.5% for each 300 meter increase in altitude.
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 1,500 meters 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.
