I recently put a rebuilt 2.1 into my '85 Westy (4400 miles ago).  It has
a good 2.1 throttle body and a rebuilt (right out of the box) 2.1 AFM
but using Digijet management system.  I'm running with the vacuum
advance/retard distributor set at TDC and, from playing with it, I can
tell you that mine will have the same idle symptoms you describe if I
advance it any more.
