High altitude operation
At high altitude, the standard carburetor air-fuel mixture will be excessively rich
Performance will decrease, and fuel consumption will increase.
High altitude performance can be improved by installing a smaller diameter main
fuel jet in the carburetor and readjusting the pilot screws. If you always operate the
generator at altitudes higher than 1,500 m (5,000 feet) above sea level, have
your authorized dealer perform these carburetor modifications.
Even with suitable carburetor jetting, engine horsepower will decrease
approximately 3.5% for each 305 m (1.000 feet) increase in altitude. The effect of
altitude on the horsepower will be greater than this if no carburetor modification is
made.
CAUTION
Operation of the generator at an altitude lower than the carburetor is jetted
for may result in reduced performance, overheating, and serious engine
damage caused by an excessively lean air/fuel mixture.
