<VV> rough running, loss of power at WOT

[Daniel Kinzelman]

Most of you know I've been experiencing rough running (feels like a miss) 
and severe loss of power at throttle openings greater than approximately 
50%.  I recently discovered with the assistance of someone running a red 
light that my car behaves as I think it should all the way to WOT when the 
engine has been running for only a very short time.  In other words, full 
throttle response was smooth and fast while the engine was still cold.  I 
presume this is due to the closed chokes enriching the mixture, indicating 
that the engine runs rough due to leaning out when the chokes are open.  I 
have since been able to duplicate this experience of full power availability 
only when the car is cold (ambient temp from about 60-70).  Once it's warmed 
up, the rough running and loss of acceleration reappears.  Let me know if 
you agree with my assessment (I'm considering rebuilding the carbs, but I 
don't yet have the parts).  If I do rebuild, should I swap jets, and if so, 
what size?  I have no idea what jets are in the car now.  Thanks.

Dan
