HIGH ALTITUDE OPERATION

At high altitude, the standard carburetor air-fuel mix- ture will be too rich. Performance will decrease, and fuel consumption will increase. A very rich mixture will also foul the spark plug and cause hard starting.

High altitude performance can be improved by specific modifications to the carburetor. If you always operate your engine at altitudes above (6,000 feet) 1,800 meters, have a engine dealer perform this carburetor modification.

Even with carburetor modification, engine horsepower will decrease about 3.5% for each 1,000 feet (300 meter) increase in altitude. The effect of altitude on horsepower will be greater than this if no carburetor modification is made. Do not operate a modified engine below 6,000 feet.
