Update: I think this is boiling down to a fuel pump issue (pun intended).

I have been thinking that the fuel pump may have been sounding just a bit funny, so I switched on the ignition while watching the fuel filter I installed just before the carbs. It was about half full after sitting for a few days, when I turned on the pump air bubbles filled the glass!

I still can't explain why it runs nice at load and RPM but falls on its face at idle, but at least I have found a problem that needs fixin'.
