EMISSIONS 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.
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 emissions control systems.
The following instructions and procedures must be followed in order to keep the emissions from your Honda engine
within the emissions standards.
Tampering and Altering
Tampering with or altering the emissions 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 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 emissions control systems on your new Honda engine were designed, built, and certified to conform with EPA,
California and Canadian emissions 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 emissions control system.
A manufacturer of an aftermarket part assumes the responsibility that the part will not adversely affect emissions
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 emissions regulations.
Maintenance
Follow the MAINTENANCE SCHEDULE on page 17. Remember 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.
