¹Power Ratings: Actual sustained equipment horsepower 
will likely be lower due to operating limitations and 
environmental factors.
†Power Ratings: All power levels are stated gross 
horsepower per SAE J2723 as rated by Kawasaki and tested 
per the SAE J1995 test standard. The gross power curves 
and more information can be viewed at www.kawasaki-
criticalpower.com.
*Power Ratings: 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. The gross power curves can be viewed at www.
BRIGGSandSTRATTON.COM. Net power values are taken 
with exhaust and air cleaner installed whereas gross power 
values are collected without these attachments. Actual 
gross engine power will be higher than net engine power 
and is affected by, among other things, ambient operating 
conditions and engine-to-engine variability. Given the wide 
array of products on which engines are placed, the gas 
engine may not develop the rated gross power when used in 
a given piece of power equipment. This difference is due to 
a variety of factors including, but not limited to, the variety of 
engine components (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.
