GENERAL INFORMATION

ENGINE MODEL:
This is a single cylinder, overhead valve
(OHV), air-cooled engine. It is a low emissions engine.
In the state of California, OHV Model Series 210000, 280000 and
310000 engines are certified by the California Air Resources
Board to meet emissions standards for 250 hours. Such

TECHNICAL INFORMATION

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:

Note: For practical operation, the horsepower loading should not
exceed 85% of rated horsepower. Engine power 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). Engine will operate
satisfactorily at an angle up to 15°.
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.
