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 specific modifications
to the carburetor. If you always operate the generator at altitudes
higher than 1,500 meters (5,000 feet) above sea level, have your
authorized Honda dealer perform these carburetor modifications.
Even with suitable carburetor jetting, engine horsepower will decrease
approximately 3.5% for each 300 meter (1,000 foot) increase in altitude.
The affect of altitude on the horsepower will be greater than this if no
carburetor modification is made.
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.
