when i first installed my BBK 65mm TB i had really bad hanging idle at about 2,000 rpms. i turned the screw in (was out about 6 turns ) all the way and only opend it back up about 1/4-1/2 a turn and no more hanging idle.

worth a try atleast

You're 100% correct. I've been playing with my idle a bit lately. If you turn the idle trim screw too far out (CCW), you WILL get a hanging idle....guaranteed. Turn it back in (CW) so it's only open about 1 full turn or less from fully closed and you're hanging idle disappears. Turning the trim screw definitely adjusts the dashpot function on these cars.

Where did you find TBs for 120, and what brand?
