ENGINE TECHNICAL INFORMATION
This is a single cylinder, overhead valve(OHV), air
cooled engine. It is a low emissions engine.
In the State of California, Model Series 210000
engines are certified by the California Air Resources
Board to meet emissions standards for 250 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 solely according
to the product and emissions warranties 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 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.

NOTE: For practical operation, the generator load
should not exceed 85% of rated wattage. Engine
gross horsepower will decrease 3-1/2% for each
1,000 feet (300 meters) above sea level and 1% for
each 10° F (5.6 ° C) above 77 ° F (25 ° C). It should
operate satisfactorily at an angle up to 15 °.
