Probiems 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 California emission regulations. We
recommend the use of genuine Honda parts whenever you have mainte-
nance 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 12. 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.
