REMOTE CONTROLS
In general, there are three types of remote controls:
Governor
Control,
Throttle
Control,
Choke-A-Matic
Control. Fig. 1 to Fig. 6, show the operation of these
control systems. See following pages for specific control
assemblies and installation hook-up by engine model.
Remote Governor Control
The Remote Governor control regulates the engine
speed by changing the governor spring tension, thus
allowing the governor to control the carburetor throttle at
all times and maintain any desired speed. Fig. 1.

Remote Throttle Control
The Remote Throttle control is used on an engine having
a fixed no load governed speed setting such as 3600 or
4000 R.P.M.
This control enables an operator to control the speed of
an engine, similar to an accelerator used on an
automobile. However, when full governed speed is
obtained, the governor prevents over speeding and
possible damage to the engine. At any point below the
governed speed, the throttle is held in a fixed position
and the engine speed will vary with the load. See Fig. 2.

Choke-A-Matic Remote Control
On Choke-A-Matic carburetors, the remote control must
be correctly adjusted in order to obtain proper operation
of the choke and stop switch.
