TECHNICAL AND CONSUMER INFORMATION

EMISSION CONTROL SYSTEM

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 uses lean carburetor settings and other systems to reduce the

emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons.

The U.S. and California Clean Air Act

EPA and California regulations require all manufacturers to furnish

written instruction describing the operation and maintenance of

emission control systems.

The following instructions and procedures must be followed in order to

keep the Honda engine emissions within the emission standards.

Tampering and Altering

Tampering with or altering the emission control system may increase

emissions beyond the legal limit. Some acts that constitute

tampering are:

• Removal or alteration of any part of intake, fuel, or exhaust system.

• 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 authorized Honda servicing dealer.

• Hard starting or stalling after starting

• Rough idle

• Misfiring or backfiring under load

• Afterburning (backfiring)

• Black exhaust smoke or high fuel consumption
