Workman MDXPage 3 -- 4Briggs & Stratton Gasoline Engine
Adjustments
Adjust Throttle Cable
NOTE: The Workman MDX is equipped with an engine
governor. Refer to the Briggs & Stratton Repair Manual
at the end of this chapter for governor information on
these machines.
Depressing the accelerator pedal rotates the engine
governor bellcrank which tensions the main governor
spring to increase engine speed. Releasing the acceler-
ator 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.
3. When the a ccelerator pedal is fully depressed the
engine governor bellcrank mechanism should have a
gap from 0.030” to 0.080” (0.8 to 2.0 mm) (Fig. 2). If nec-
essary, adjust jam nuts on accelerator cable so that gap
is correct.
4. After throttle cable adjustment is correct, lower and
secure cargo box.
