I've had stuck float valves, but under those conditions it's really hard to
get anywhere at all.  You can set up a mirror and a flashlight, and have a
partner (in full Nomex gear) watch for fuel drizzling out while it's
running.  A blown power valve can make the car run awfully rich too, and a
power valve set at 6.5" vacuum with a super rumpety cam can pulse extra fuel
in the carb at idle since the valve will see low enough vacuum to open.

Have you checked your timing to see if it's spot on?  I had what I thought
was a carburetor problem, but most of it was my timing was retarded.  After
adjusting the timing my car ran pretty good, if a little rich.  It had
drifted off because the bolt was snug but not snug enough on the
distributor.  At least it gave me a good base line.
