DASH
POT
SYSTEM

These

carburetors
are

equipped

with
a
dash

pot
interlocked
with
the

primary
thrott
Ie
valve

through
a

link

mechanism

The
dash

pot
prevents
the

throttle

valve

from

closing
abruptly
thereby

reducing
He
emissions

during
deceleia

tion
or

gear
shifting

In
automatic

transmissi9fi
models

it

also

prevents
engine
stall

resulting

from

quick
application
of
the
brake
or

from

quick
release
of
