or no choking will be needed when the engine iswarm.
Place the throttle lever half-way between
"SLOW" and "FAST",
Place the throttle lever half-way between
"SLOW" and "FAST".
6. To start the engine the clutch-brake pedal must
be pressed all the way down and the power
take-off clutch handle must be in the disengaged
position to actuate the safety starting switches.
On the I nternational Cub Cadet 129, 149, and 169
Tractors the speed control lever will return to
neutral wher the clutch-brake pedal is pressed all
the way down.
International Cub Cadet 86, 108, and 128 Trac-
tors: Check to see that the gearshift lever is in the
neutral position.
STARTING THE ENGINE
Be sure there is an adequate supply of gasoline
in the fuel tank.
A CAUTION! Never remove the fuel tank
cap or fill the fuel tank when the engine
is running, is hot, or indoors. Also, do
not smoke when working around inflammable fuel.
Be sure the fuel shut-off valve is open.
All Models: Turn the ignition key clockwise to the
"ST ART" position and release it as soon as the
engine starts; however do not operate the motor
generator for more than 30 seconds at anyone
time. If the engine does not start within this time,
turn the key "OFF" and wait a few minutes, then
try again.
5. 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

FUEL SYSTEM
This engine is designed to operate on leaded
gasoline with a 93 minimum octane rating or on
unleaded or low lead gasoline with a 91 minimum
octane rating (Research Method).
use of unleaded gasoline will lengthen spark
plug and valve life, maintain engine performance
longer, and reduce rust and corrosion of engine
wh ile stored.
The fuel tank filler cap has an air vent. Keep the
vent open at all times to assure proper flow of thefuel.
A CAUTION! Never remove the fuel tank cap
or fill the fuel tank when the engine is
running, 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 under the fuel tank isopen.
Screw out the needle stem (shut-off valve)
until the seat on the stem is tight against the stop
to prevent leakage or seepage when the valve is in
its full-open position.
CARBURETOR ADJUSTMENTS
The carburetor is adjusted at the factory and under
normal operation conditions it will not require
readjusting. However, if the engine does not
operate properly, it is recommended a new air
cleaner be installed before performing carburetor
adjustments. If this adjustment has been disturbed
for any reason, proceed as follows:

CARBURETOR ADJUSTMENTS -Continued
A CAUTION! Be sure the brake pedal is in
the locked position, transmission is in
neutral, and the mower is disenga~d
before adjusting the carburetor.
Adjusting the High-Speed Adjustment Screw
Turn the high speed adjustment screw counterclockwise approximately two turns from the closed
position and start the engine.
Be sure the choke is fully open when adjusting.
After the engine has reached normal operating
temperature, place the throttle lever in the fast
position and turn the high speed adjustment screw
clockwise to the leanest mixture that will allow
sat i sf actory acceleration and steady governor
operation. Then, turn counterclockwise to the
richest mixture that allows satisfactory operation.
The difference between the rich and lean points is
about 1/2 turn. Set the mixture to the rich end of
this range.
If the engine shows a sooty exhaust and is sluggish
under load, the high speed mixture is too rich. The
high speed adjustment screw must be turned
clockwise 1/4 turn at a time until the condition is
corrected.
Adjusting the Idle Adjustment Screw
After the high speed adjustment screw is adjusted,
it may be necessary to readjust the idle adjustment
screw as each affects the other.
Close the idle adjustment screw to its seat by
turning it clockwise; then open it one turn. Start
the engine and operate it at fast idling speed
(without any load) until thoroughly warm.
While the engine is running at fast idle speed, it is
advisable to screw in the throttle stop screw a few
turns to keep the engine from stopping when the
throttle lever is moved to the fully retarded
"SLOW" position. The engine will then be idling at
a fairly high speed and the throttle stop screw can
be backed out a little at a time until the desired
idle speed is obtained.
If the engine misses and backfires under load, the
high speed mixture is too lean. The high speed
adjustment screw must be turned counter-clock-
wise 1/4 turn at a time until the condition is
corrected.
PREPARING THE TRACTOR FOR EACH DAY'S WORK
Check the crankcase oil level and add new oil if necessary. See pages 34 and 35.
Clean the air cleaner element if necessary. See page 21.
Inspect the tires for general condition. See page 26
If the engine misses or rolls while backing out the
throttle stop screw, the idle adjustment screw may
be adjusted in or out until the engine operates
smoothly. Speed up the engine for a few seconds;
then recheck the idle adjustment. A slight adjust-
ment in or out will give the smoothest idle.
11
Retighten the cap screws after the seat is adjusted.
NOTE: The battery is located in a well under the
operator's seat for ease in servicing or replacement
when necessary.
CLUTCH AND BRAKE PEDAL
Adjusting the seat.
Before starting the tractor, adjust the seat to the
most comfortable driving position. Tile the seat
forward over the steering wheel, loosen the four
cap screws in the seat support, and slide the seat
assembly forward or rearward to the position
wh ich is most comfortable for the operator.
