* Power Rating
The gross power rating for individual gasoline engine models is labeled in accordance with SAE (Society of
Automotive Engineers) code J1940 Small Engine Power & Torque Rating Procedure, and is rated in accordance
with SAE J1995. Torque values are derived at 2600 RPM for those engines with “rpm” called out on the label and
3060 RPM for all others; 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 variabil-
ity. Given the wide array of products on which engines are placed, the gasoline 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 includ-
ing, 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 engine.
