ENGINETECHNICALiNFORtViATION
This is a single cylinder, overhead valve (OHV), air cooled
engine, it is a iow emissions engine.
In the State of Caiifornia, 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 respectto the performance or
operational life of this engine. The engine is warranted soidy
according to the product and emissions warranties stated
elsewhere in this manual=
Power Ratings
The gross power rating for individuaI 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 accordancewith SAEJ1995
(Revision 2002=05). Torque values are derived at 3060 RPM;
horsepower values are derived at 3600 RPM. Actuai gross
engine power wiii be lower and is affected by, among other
things, ambient operating conditions and engine-to-engine
variabiiity. Given both the wide array of products on which
engines are placed and the variety of environmental issues
appiicabb to operating the equipment, the gas engine wiii 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 cteaner, exhaust, charging,
cooiing, carburetor, fuel pump, etc.), appiication iimitations,
ambient operating conditions (temperature, humidity,
altitude), and engine-to-engine variabiiity. Due to
manufacturing and capacity iimitations, Briggs & Stratton
may substitute an engine of higher rated power for this
Series engine.

NOTE:For practicai operation, the engine ioad should not
exceed 85% of rated power. Engine power will decrease
3-I/2% for each 1,000 feet (300 meters) above sea Ievei and
1% for each 10° F (5.6° C) above 77° F (25° C). It should
operatesatisfactorily at an angle up to 15°.
