Sunday afternoon, I fiddled with the carbs a bit; closed the mixture screws on the front/back carbs, effectively cutting them out of the idle circuit - also closed the throttle plates; they were originally opened about 1/2 turn of the screw.

To achieve idle, had to open throttle plate on center carb about 1 full turn on the screw and richen up the mixture screws by about 3/4 turn each.

Checked the fuel filter, no problems there...

Car is idling great (just a little rich) at 1000rpm and is accelerating fine through all the gears. Had a new (small) problem with the carb linkage binding, but got that sorted out.

Still not sure what the problem was... by closing the throttle plates on the front/back carbs, it would just mean that they open a little later during acceleration. The mixture screws should'nt have had any effect, because they only affect idle (or am I missing something?). Maybe the plates were just getting stuck open, who knows...

Thanks for all the input.
