High altitude operation
Operation of the rotary mower 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.
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 rotary mower at altitude
higher than 1,500 m (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 m (1,000 foot) increase in altitude.
The effect of altitude on horsepower will be greater than this if no
carburetor modification is made.
