4.9- High altitude operation
At high altitude, the standard carburetor air-fuel mixture 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 pump at altitudes above 6,000 feet (1,800 meters) have an authorized
water pump dealer perform this carburetor modification.
In any case, engine horsepower will decrease about 3to5% for each 1,000 feet (300m) increase in
altitude.
Note: 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 6,000 feet (1,800 meters) with a
modified carburetor may cause the engine to overheat and result in serious engine damage.
For use at low altitudes, have an authorized water pump dealer return the carburetor to original
factory specifications.
