Engines equipped with automatic transmissions require
an anti-stall device as protection against loading the
engine when the accelerator pedal is suddenly depressed
and released. This protection is provided by the dashpot.
The dashpot retards the closing rate of the throttle plate
as it approaches the idle position, allowing the engine to
dissipate the raw fuel discharged into the intake manifold
by the accelerating pump.
The dashpot slows the final phases of throttle plate
closing by means of a spring-loaded diaphragm. When
the accelerator pedal is released, the throttle return spring
in the throttle linkage closes the throttle plate
simultaneously with the release of the pedal. As the
throttle plate approaches the idle position, a tab on the
throttle lever contacts the lower edge of the dashpot
lever. This rotates the dashpot lever, causing the head of
the dashpot adjusting screw of the dashpot lever
