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, fuel, engine lubrication, maximum
governed engine speed, individual engine to engine
variability, design of 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.
