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 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 engine.
