TECHNICAL INFORMATION
POWER RATINGS: The power ratings for an individual engine
model are initiallydevelopedby startingwith SAE (Societyof Auto-
motive
Engineers)
code J1940
(Small Engine
Power &
Torque
Rating Procedure) (Revision 2002-05).
Given boththe wide array
of
products on
which
our
engines
are placed,
andthe
variety
ofen-
vironmentalissuesapplicableto operatingthe equipment,it may
be that the
engine
you have
purchased
wilt not
develop
the rated
horsepower
whenusedin
a piece
of power
equipment (actual
"on-
site"power).This differenceisdue to a varietyof factors including,
but not limited to, the
following:
differences in
altitude, tempera-
ture, barometric pressure, humidity, fuel, engine lubrication, maxi-
mum governed engine speed, individual engine to engine variabil-
ity, 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.
