You mention =E2=80=9Cidling=E2=80=9D below but is that at 2,000 RPM as =
initially stated (or has that ben solved)?  Does the car idle properly =
(assumed 600-800 RPM) once it is warmed up?  It might be that the idle =
adjustment screw (for the throttle, not the idle fuel mixture) is not =
adjusted properly.  When the choke is =E2=80=9COn=E2=80=9D there is a =
stepped piece that opens the primary throttle plates (more than the =
normal idle position). So, where as when the choke plate closes at the =
top..., the throttle plates open more than normal.  This may be why the =
car is starting and running at 2,000 RPM. However, when you open the =
choke the stepped idle speed piece moves to a position where the =
throttle plates are (fully) closed and the engine dies.

It's definitely a vacuum leak.  I plugged up all of the ports on the =
carb and the port on the intake manifold that goes to the break booster =
and nothing changed.  So I pulled off the carb and the spacer that goes =
between the carb and the manifold and looked it over really good and =
didn't see anything obvious.  I reinstalled the carb without the spacer =
and it runs fine now.  I'm waiting for it to cool down and I'll put the =
spacer back in and see what happens.  =20

Of course, while I had it idling I noticed that the temperature gauge on =
the dash was getting over 225.  I'm not sure how accurate that is and it =
never boiled over.  I'll get out my laser temp gun and poke around a =
little bit. =20

Thanks for everybody's guidance.
