NFORMATION

The U.S. Environmental Protection Agency (and Califor-
nia Air Resource Board for equipment certified to CA 
standards) requires that this engine comply with exhaust 
and evaporative emission standards. Locate the emis-
sions compliance decal on the engine to determine what 
standards the engine meets, and to determine which 
emissions warranty applies. The engine is certified to 
meet the applicable emission standards on gasoline. It is 
important to follow the maintenance specifications in the 
Maintenance section to ensure that the engine complies 
with the applicable emission standards for the duration of 
the product’s life. This engine utilizes lean carburetion 
settings and other systems to reduce emissions. Tamper-
ing with or altering the emission control system may 
increase emissions and may be a violation of Federal or 
California Law. Acts that constitute tampering include but 
are not limited to:

• 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

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
