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 Series 110000
and 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. This engine is
warranted solely according to the product and
emissions warranties stated elsewhere in this
manual.
Model, Type and Code Number
To get replacement parts or technical assistance in the
future write your engine Model, Type and Code number
along with the date of purchase here. These numbers
are located on your engine. For the location, see

Technical Information
Power Ratings: The power ratings for an individual
engine model are initially developed by starting with
SAE (Society of Automotive Engineers) code J1940
(Small Engine Power & Torque Rating Procedure)
(Revision 2002-05). Given both the wide array of
products on which our engines are placed, and the
variety of environmental issues applicable to operating
the equipment, it may be that the engine you have
purchased will not develop the rated horsepower when
used in a piece of power equipment (actual "on-site"
power). This difference is due to a variety of factors
including, but not limited to, the following: differences in
altitude, temperature, barometric pressure, humidity,

Note: For practical operation, the horsepower loading
should not exceed 85% of rated horsepower. 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°.

the particular piece of power equipment, the manner in
which the engine is operated, engine run-in to reduce
friction and clean out of combustion chambers,
adjustments to the valves and carburetor, and other
factors. The power ratings may also be adjusted based
on comparisons to other similar engines utilized in
similar applications, and will therefore not necessarily
match the values derived using the foregoing codes.
