TECHNICAL INFORMATION
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.
• Engine speed instability.
• 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 California emission
regulations. We recommend the use of Honda Genuine 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 52. 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 dusty conditions, will require more frequent service.
