GOVERNOR SPEED CONTROL ADJUSTMENTS
The acceptable operating speed range is 1800 to 3600 RPM.
Idle speed is 1750 RPM. The manufacturer of the
equipment on which the engine is used, specifies the top
governed no load speed at which the engine may be
operated. DO NOT EXCEED this speed.
To increase engine speed move control in direction shown
by arrow. Refer to illustration.
GENERAL INFORMATION
These engines are single cylinder, L-head, air-cooled type.

The horsepower ratings listed above are established in
accordance with the Society of Automotive Engineers Test
Code-J607.
For practical operation, the horsepower
loading should not exceed 85% of these ratings. Engine
power will decrease 3'/^% for each 1,000 feet (304.8 m)
above sea level and 1% for each 10® above 60® F (16® C).
In some areas, local law requires the use of a resistor spark
plug so as to suppress ignition signals. If an engine was
originally equipped with a resistor spark plug, be sure to
use the same type of spark plug for replacement.

STORAGE INSTRUCTIONS
Engines to be stored over 30 days should be completely
drained of fuel to prevent gum deposits forming on
essential carburetor parts, fuel filter and tank.
Note: The use of a fuel additive, such as STA-BIL, or an
equivalent, will minimize the formation of fuel gum deposits
during storage. Such an additive may be added to the
gasoline in the fuel tank of the engine, or to the gasoline
in a storage container.
a. All fuel should be removed from the tank. Run the engine
until it stops from lack of fuel. The small amount of fuel
that remains In the sump of the tank should be removed
by.absorbing it with a clean, dry cloth.
b. While engine is still warm, drain oil from crankcase.
Refill with fresh oil.
c. Remove spark plug, pour one ounce (29.6 cc) of engine
oil into cylinder and crank slowly to distribute oil.
Replace spark plug.
d. Clean dirt and chaff from cylinder, cylinder head fins,
blower housing, rotating screen and muffler areas.
e. Store in a clean and dry area.
