Power Ratings
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 variability. Given the wide array of products on which engines are placed, the gasoline engine
