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 1,500 meters (5,000 feet), 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 (1,000 feet) increase in
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.
Emission Control System Information
Emission Control System Warranty
Your new Honda complies with both the U.S. EPA and State of
California emission regulations. American Honda provides the
same emission warranty coverage for Honda Power Equipment
engines sold in all 50 states. In all areas of the United States, your
Honda Power Equipment engine is designed, built, and equipped
to meet the U.S. EPA and California Air Resources Board emission
standard for spark ignited engines.

Warranty Coverage
Honda Power Equipment engines certified to CARB and EPA
regulations are covered by this warranty to be free from defects in
materials and workmanship that may keep it from meeting the
applicable EPA and CARB emissions requirements for a minimum
of 2 years or the length of the Honda Power Equipment
Distributor's Limited Warranty, whichever is longer, from the
original date of delivery to the retail purchaser. This warranty is
transferable to each subsequent purchaser for the duration of the
warranty period. Warranty repairs will be made without charge for
diagnosis, parts, and labor. Information about how to make a
warranty claim, as well as a description of how a claim can be
made and/or how service can be provided, can be obtained by
contacting an authorized Honda Power Equipment dealer or by
contacting American Honda at the following:
Email: powerequipmentemissions@ahm.honda.com
Telephone: (888) 888-3139
The covered components include all components whose failure
would increase an engine's emissions of any regulated pollutant
or evaporative emissions. A list of specific components can be
found in the separately included emissions warranty statement.
Specific warranty terms, coverage, limitations and manner of
seeking warranty service are also set forth in the separately
included emissions warranty statement. In addition, the emissions
warranty statement can also be found on the Honda Power
equipment website or at the following link:

Source of Emissions
The combustion process produces carbon monoxide, oxides of
nitrogen, and hydrocarbons. Control of hydrocarbons and oxides of
nitrogen are 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 Canada
EPA, California, and Canadian 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 keep the emissions from your Honda engine within the
emission standards.
Tampering and Altering
Tampering is a violation of federal and California law.
Tampering with or altering the emission control system may
increase emissions beyond the legal limit. Among those acts that
constitute tampering are:
• Removal or alteration of any part of the intake, fuel, or exhaust
systems.
• Altering or defeating the governor linkage or speed-adjusting
mechanism to cause the engine to operate outside its design
parameters.
Problems That May Affect Emissions
If you are aware of any of the following symptoms, have your
engine inspected and repaired by your servicing dealer.
• Hard starting or stalling after starting.
