Workman MD
Single Cylinder Gasoline Engine
Page 4 -- 5
Adjust Throttle Cable (Serial Numbers Above 313000400)
NOTE:
Workman MD vehicles with serial numbers
above 313000400 use the engine governor to control
engine speed. Refer to the Kohler Service Manual at the
end of this chapter for governor information on these
machines.
Depressing the accelerator pedal rotates the engine
mounted throttle lever which tensions the engine gover-
nor spring to increase engine speed. Releasing the ac-
celerator pedal decreases governor spring tension to
reduce engine speed.
1. Park machine on a level surface, stop engine, en-
gage parking brake and remove key from the ignition
switch.
2. Lift cargo box and prop with rod to gain access to the
engine (Fig. 3).
3. Make sure that shift lever is in the neutral position to
prevent the machine from moving.
NOTE:
If phototac is to be used to measure engine
speed, DO NOT use driven clutch on transaxle for speed
measurement.
4. With ignition switch in the RUN position, depress ac-
celerator pedal and allow engine to start. Fully depress
accelerator pedal and have a second person measure
engine speed with a tachometer. With pedal fully de-
pressed, engine speed should be from
3250 to 3350
RPM
. If necessary, adjust jam nuts on throttle cable so
that engine speed is correct when the accelerator pedal
is fully depressed.
5. After throttle cable adjustment is correct, lower and
secure cargo box.
