Engine Power Rating Information: 

The gross power rating for individual gas engine models is labeled in accordance with SAE

(Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure), and rating performance has
been obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Torque values are derived at 3060 RPM;
horsepower values are derived at 3600 RPM. Actual gross engine power will be lower and is affected by, among other things,
ambient operating conditions and engine-to-engine variability. Given both the wide array of products on which engines are
placed and the variety of environmental issues applicable to operating the equipment, the gas engine will not develop the rated
gross power when used in a given piece of power equipment (actual "on-site" or net power). This difference is due to a variety
of factors including, but not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.),
application limitations, ambient operating conditions (temperature, humidity, altitude), and engine-to-engine variability.  Due to
manufacturing and capacity limitations, Briggs & Stratton may substitute an engine of higher rated power for this Series
engine.

Models and specifications are subject to change without notice.
