ENGINE
Engine Power Rating Information
The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of Automotive Engi-
neers) code J11940 (Small Engine Power & Torque Rating Procedure), and rating performance has been obtained and
corrected in accordance with SAE J1995 (Revision 2002-5). 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 prod-
ucts 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
horsepower). 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, humid-
ity, altitude), and engine-to-engine variability. Due to manufacturing and capacity limitations, Briggs & Stratton may sub-
stitute an engine of higher rated power for this Series engine.
NOTE: All component dimensions given in U.S. inches
1 inch = 25.4 mm
