Check the distributor a little more closely, as you may have one
or both of the governor weight springs broken.  This kills the
centrifugal advance and has the effect you describe on
accelleration.  This has occurred on two family Colt/Champs of
79-80 vintage.  (Expect to pay about $50 from Chrysler for a
replacement governor assembly.)  You can check whether you are
getting any centrifugal advance with a timing light.  Cut off
the vacuum advance and rev the engine to about 2000 rpm.  You
should get about 20 degrees or more of advance over the idle
reading.  If you get no advance, then the governor is the
problem.

Another general cause of accelleration hesitation or stumble is
a vacuum leak somewhere below the throttle plates.  Check all
hoses taking vacuum off the intake manifold, as one could be 
cracked and causing the problem.  

As a final word of advice, find another place to get your car
worked on, as it sounds like the boys at the ``carb shop'' are
just guessing.
