Carburetor Modification For High Altitude Operation; Transporting - Honda WMP20XE Manual Del Propietário

CARBURETOR MODIFICATION FOR 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.
Operation at an altitude that differs from that at which this engine was
certified, for extended periods of time, may increase emissions.
High altitude performance can be improved by specific modifications
to the carburetor. If you always operate your pump at altitudes above
1,500 meters, have your servicing dealer perform this carburetor
modification. This engine, when operated at high altitude with the
carburetor modifications for high altitude use, will meet each emission
standard throughout its useful life.
Even with carburetor modification, engine horsepower will decrease
about 3.5% for each 300-meter increase in altitude. The effect of
altitude on horsepower will be greater than this if no carburetor
modification is made.
NOTICE
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 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.
