6) 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 engine
at attitudes higher than 5000 feel (1500 meters) above sea level, have an authorized
generator dealer perform this carburetor modification.
Even with suitable carburetor 」 etting, engine horsepower will decrease approximately
3.5% for each 1000 foot (300 meter) increase in altitude. The effect of altitude on
horsepower will be greater than this if no carburetor modification is made.
