ENGINE TECHNICAL INFORMATION
This is a single cylinder, overhead valve (OHV), air
cooled engine. In the State of California, Model 120000
engines are certified by the California Air Resources
Board to meet emissions standards for 125 hours.
Such certification does not grant the purchaser, owner
or operator of this engine any additional warranties with
respect to the performance or operational life of this
engine. The engine is warranted solely according to the
product and emissions warranties stated elsewhere in
this manual.
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 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.
