MTD 145-660A User Manual

Finai Adjustment: Turn needle valve in until engine
misses (lean mixture) then turn it out past smooth op¬
erating point until engine runs unevenly (rich mix¬
ture). Now turn needle valve to the mid-point between
rich and lean so the engine runs smoothly. Hold throt¬
tle at idle position and set idle speed adjusting screw
until fast idle is obtained (1750 RPM). Hold throttle in
idle position and turn idle valve in (lean) and out
(rich) until engine idles smoothly. Then reset idle
speed adjusting screw so that engine idles at 1750
RPM. Release throttle—engine should accelerate with¬
out hesitation or sputtering. If engine does not accel¬
erate properly, the carburetor should be re-adjusted
to a slightly richer mixture.
CHOKE-A-MATIC CARBURETOR CONTROL
ADJUSTMENTS
Proper choke and stop switch operation is dependent
upon proper adjustment of remote control on the pow¬
ered equipment.
To Check Operation of Choke-A-Matic Controls:
a. Remove air cleaner.
b. Move remote control lever to CHOKE position. The
carburetor choke should be closed.
c. Move remote control to STOP position. Lever should
make good contact with stop switch.
To Adjust:
Place remote control lever on equipment in FAST (high
speed) position. Loosen control casing clamp screw
"B". Move control casing "A" and wire until lever "D"
touches choke operating link at "C". Tighten casing
clamp screw "B". Replace air cleaner.
OFF-SEASON STORAGE
If the machine is to be inoperative for a period longer
than 30 days, the following precautions are recom¬
mended:
Step 1. Working outdoors, drain all fuel from the
fuel tank. Use a clean dry cloth to absorb
the small amount of fuel remaining in the
tank, then run the engine until all fuel in car
buretor is exhausted.
^ WARNING ^
Do not drain fuel while smoking, or
if near an open fire.
Step 2. Drain all the oil from the crankcase (this
should be done after the engine has been
operated and is still warm) and refill the
crankcase with clean new oil.
Step 3. Disconnect the spark plug wire and remove
the spark plug from the cylinder. Pour about
six drops of engine oil into the cylinder and
then pull the recoil starter several times to
spread the oil on the cylinder wall. Replace
the spark plug, but DO NOT connect the wire.
Step 4. Clean the engine and the entire mower thor¬
oughly.
Step 5. Lubricate all lubrication points indicated in the
Maintenance Section, then wipe the entire
machine with an oiled rag in order to protect
the surfaces.
WHEEL SPACERS
The spacers on the rear wheels must be on the outside
of the wheels as shown in figure 42 when using th<
mowing deck.
If tire chains or a draw bar hitch is used on the tracto
it will be necessary to remove the cotter pins, spacer
and wheels. Place the spacers on the axles and secur
with the cotter pins.
NOTE
You cannot operate the tractor with
mowing deck when the spacers are
installed on the inside of the wheels.
