TECHNICAL INFORMATION
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 (temper-
ature, 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.
GENERAL INFORMATION
This is a single cylinder, L-head, air-cooled engine. It is a low
emissions engine.
In the state of California, the 120000 engines covered in this
manual 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.

Note: Engine power will decrease 3-1/2% for each 1,000 feet
(300 meters) above sea level and 1% for each 105 F
(5.65 C) above 775 F (255 C). It will operate satisfac-
torily at an angle up to 155. Refer to the equipment op-
erator manual for safe allowable operating limits on
slopes.
SAFETY SPECIFICATIONS
BEFORE OPERATING
ENGINE
• Read entire Operating & Maintenance Instructions AND
the instructions for the equipment this engine powers.*
• Failure to follow instructions could result in serious injury
or death.
* Briggs & Stratton does not necessarily know what equip-
ment this engine will power. For that reason, you should
carefully read and understand the operating instructions for
the equipment on which your engine is placed.
THE OPERATING &
MAINTENANCE INSTRUCTIONS
CONTAIN SAFETY
INFORMATION TO:
• Make you aware of hazards associated with engines
• Inform you of the risk of injury associated with those
hazards, and
• Tell you how to avoid or reduce the risk of injury.
A signal word (DANGER, WARNING, or CAUTION) is used
with the alert symbol to indicate the likelihood and the potential
severity of injury. In addition, a hazard symbol may be used to
represent the type of hazard.
DANGER indicates a hazard which, if not avoided,
will result in death or serious injury.
WARNING indicates a hazard which, if not avoided,
could result in death or serious injury.
CAUTION indicates a hazard which, if not avoided,
might result in minor or moderate injury.
,
CAUTION when used without the alert symbol,
indicates a situation that could result in damage to
the engine.
