OPERATING THE ENGINE
STARTING THE ENGINE
1. Be sure the fuel shut-off valve is open.
Z. Pull the choke control button all the way
out (see I Musi. 5 or 6). More or less choking may
be necessary due to variations in temperature,
grade of fuel, etc. Little or none will be
needed when the engine is warm.
3. Place the throttle lever halfway between
"SLOW^' and 'TAST'\ See IMust. 5 or 6.
4. To start the engine the clutch-brake
pedal must be pressed all the way down to ac¬
tivate the safety starting switch.
On the International Cub Cadet 107, 127, ond 147
Troctors the speed control lever will return to
neutral when the clutch brake pedal is pressed
all the way down.
International Cub Codet 73, 106, and 126 Tractors:
Check to see that the gearshift lever is in the
neutral position. See lllust. S.
All Models: Turn the ignition key clockwise
to the ''START'* position and release it as soon
as the engine starts; however do not operate
the motor-generator for more than 30 seconds
at any one time. If the engine does not start
within this time, turn the key "OFF" and wait
a few minutes, then try again.
3. After the engine starts, slowly release
the clutch-brake pedal and gradually push the
choke control button all the way in. Do not use
the choke to enrich the fuel mixture, except
when necessary to start the engine.
STOPPING THE ENGINE
Move the throttle lever to the "SLOW" po¬
sition and allow the engine to idle for a short
time before stopping. Then turn the key to the
"OFF" position.
FUEL SYSTEM
FUEL SYSTEM
Fill the fuel tank with clean, fresh, regular
grade gasoline, preferably at the end of each
day's use. This will force out any moisture¬
laden air and prevent condensation in the fuel
tank. Do not mix oil with the gosoline.
The fuel tank filler cap has an air vent.
Keep the vent open at all times to assure
proper flow of the fuel.
Coufionl Never remove the fuel tank cap or
fill the fuel tank when the engine is running,
is hot, or when near an open flame. Do not
smoke when working around inflammable fuel,
as the air around the tractor is mixed with a
highly explosive vapor. When pouring fuel,
keep the container or hose nozzle in contact
with the metal of the fuel tank to avoid the
possibility of an electric spark igniting the
gas. Do not spill gasoline on a hot engine.
FUEL SHUT-OFF VALVE
Be sure the shut-off valve on the fuel
strainer under the gasoline t^ulk is open.
Screw out the needle stem (Shut-off valve) un¬
til the seat on the stem is tight against the
stop
to prevent leakage or seepage when the
valve is in its full-open position.
CLEANING THE FUEL STRAINER AND SEDIMENT BOWL
After every 25 hours of operation, clean
the fuel strainer as follows:
1. Close the shut-off valve. See lllusts. 10 and
10A. Loosen the knurled nut under the sediment
bowl and remove the bowl and screen.
2. Cle«Ln the sediment bowl and screen.
3. When reassembling, be sure the gasket
between the bowl and the main body is in good
condition and does not leak. Use a new gasket
if necessary.
CARBURETOR ADJUSTMENTS
The carburetor is adjusted at the factory
and under normal operating conditions it will
not require readjusting. However, if the engine
does not operate properly, it is recommended
a new air cleaner be installed before per¬
forming carburetor adjustments. If this ad¬
justment has been disturbed for any reason,
proceed as follows:
