ENGINE TECHNICAL
INFORMATION
This is a single cylinder, air cooled engine. It is a low
emissions engine.
In the State of California, these water pump engines
are certified by the California Air Resources Board to
meet emissions standards for 50 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 as stated elsewhere
in this manual.
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.
