Carburetor Modifications for High Altitude Operation

At high altitude, the standard carburetor air-fuel mixture will be
too rich. Performance will decrease, and fuel consumption will

high altitude use, will meet each emission standard throughout its

faulty components Even with carburetor modification, engine horsepower will

altitude. The effect of altitude on horsepower will be greater than
this if no carburetor modification is made.
When the carburetor has been modified for high altitude operation,
the air-fuel mixture will be too lean for low altitude use. Operation
at altitudes below 1,500 meters (5,000 feet) with a modified
carburetor may cause the engine to overheat and result in serious
engine damage. For use at low altitudes, have your servicing
dealer return the carburetor to original factory specifications.
