* Engine power will decrease 3-1/2% for each 1,000 feet (300
meters) above sea level and 1% for each 10° F (5.6° C) above
77° F (25° C). It will operate satisfactorily at an angle up to 15°.
Refer to the equipment operator’s manual for safe allowable
operating limits on slopes.

Repair Manual P/N 272147.
nWe recommend that you use an authorized Briggs & Stratton
Service Dealer for all maintenance and service of the engine and
engine parts. Use only genuine Briggs & Stratton parts.
General Information
This is a single cylinder, overhead valve (OHV)
air-cooled engine. It is a low emissions engine.
In the state of California, OHV Model 120000 and
150000 engines are certified by the California Air
Resources Board to meet emissions standards for
125 hours. OHV Model 200000 and 210000 engines
are certified by the California Air Resources Board to
meet emissions standards for 250 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. This engine is warranted solely according to
the product and emissions warranties stated
elsewhere in this manual.
Engine Power Rating Information
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. Actual gross engine
power will be lower and is affected by, among other
things, ambient operating conditions and
engine-to-engine variability. Given both the wide array
of products on which engines are placed and the
variety of environmental issues applicable to
operating the equipment, the gas engine will not
develop the rated gross power when used in a given
piece of power equipment (actual “on-site” or net
power). This difference is due to a variety of factors
including, but not limited to, accessories (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.
