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 lean carburetor settings and other 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. Clean Air Acts and Environment Canada
EPA 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 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 . 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.

The power rating of the engine indicated in this document is the
net power output tested on a production engine for the engine
model and measured in accordance with SAE J1349 at 3,600
rpm (Net Power) and at 3,600 rpm (Max. Net Torque). Mass
production engines may vary from this value.
Actual power output for the engine installed in the final machine
will vary depending on numerous factors, including the
operating speed of the engine in application, environmental
conditions, maintenance, and other variables.
