3. Turn the fuel valve OFF position.

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 screw. If you always operate the
generator at altitudes higher than 6,000 feet above sea level, have your authorized
Honda Generator dealer perform these carburetor modifications.
Even with suitable carburetor jetting, engine horsepower will decrease approximatery
3.5% for each 1,000 foot increase in altitude. The affect of altitude on 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.
