TECHNICAL INFORMATION
SERIAL NUMBER AND TYPE LOCATION
Record the engine serial number and type in the space below. You will 
need this information when ordering parts and when making technical 
or warranty inquiries.
Date purchased: ____________________
RADIO FREQUENCY INTERFERENCE LABEL (CANADA)
This engine complies with Canadian radio frequency interference 
regulations, ICES-002. 
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-foot) 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 (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
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 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 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.
• Rough idle.
• Misfiring or backfiring under load.
• Afterburning (backfiring).
• Black exhaust smoke or high fuel consumption.
Replacement Parts
The emission control systems on your Honda engine were designed, 
built, and certified to conform with EPA, California, and Canadian 
emission regulations. We recommend the use of genuine Honda parts 
whenever you have maintenance done. These original-design 
replacement parts are manufactured to the same standards as the 
original parts, so you can be confident of their performance. The use 
of replacement parts that are not of the original design and quality 
may impair the effectiveness of your emission control system.
A manufacturer of an aftermarket part assumes the responsibility that 
the part will not adversely affect emission performance. The 
manufacturer or rebuilder of the part must certify that use of the part 
will not result in a failure of the engine to comply with emission 
regulations.
Maintenance
Follow the maintenance schedule on page 6. Remember that this 
schedule is based on the assumption that your machine will be used 
for its designed purpose. Sustained high-load or high-temperature 
operation, or use in unusually wet or dusty conditions, will require 
more frequent service.
