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 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 engine at altitudes above
2,000 feet (610 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 1,000-foot (300-meter) increase in altitude. The
effect of altitude on horsepower will be greater than this if no
carburetor modification is made.
When auto throttle type engines are used in high altitude applications,
the ability to idle down to 2500 rpm could be diminished. See your
servicing dealer for information on adjustments if your auto throttle
unit does not idle down with the load released or has trouble returning
to full rpm with the load applied.
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 2,000 feet (610 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.
Emission Control System Information
Source of Emissions
The combustion process produces carbon monoxide, oxides of
nitrogen, and hydrocarbons. Control of hydrocarbons and oxides of
nitrogen is very important because, under certain conditions, they
react to form photochemical smog when subjected to sunlight. Carbon
monoxide does not react in the same way, but it is toxic.
Honda utilizes appropriate air/fuel ratios and other emissions control
systems to reduce the emissions of carbon monoxide, oxides of
nitrogen, and hydrocarbons. Additionally, Honda fuel systems utilize
components and control technologies to reduce evaporative
emissions.
The U.S., California Clean Air Act, and Environment & Climate
Change Canada
EPA, California, and Canadian emissions regulations require all
manufacturers to furnish written instructions describing the operation
and maintenance of emission control systems.
The following instructions and procedures must be followed in order to
TYPE
keep the emissions from your Honda engine within the emission
standards.
Tampering and Altering
NOTICE
Tampering is a violation of federal and California law.
