ENGINE TECHNICAL INFORMATION
This is a single cylinder, L-head, air cooled engine. It is a low
emissions engine.
In the State of California, Model Series 90000 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 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). 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 horsepower). 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.

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°.
