Emissions Information

The U.S. Environmental Protection Agency

(and California Air Resource Board for

equipment certified to CA standards) requires

that this engine comply with exhaust and

evaporative emission standards. Locate the

emissions 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

verify 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. Tampering 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.
