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 lim-
ited to, the following: differences in altitude, temperature, barometric pressure, humidity, fuel, engine lubrication, max-
imum governed engine speed, individual engine to engine variability, design of the particular piece of power equip-
ment, 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.
