I'm about 360* in from fully CCW now and it seems to run O.K., some times after a long red light I see a cloud of fuel smoke as I pull away from a stop, others not .

What color is the smoke? Because of how the diesel operates, if it was going to smoke at idle, it would do it all the time, not after a delay of sitting at a light. Rich (injection quantity) smoke is black. Injection/Timing smoke is grey or white. Oil smoke is blue/grey. Based on the red light statement, I'd be more inclined to suspect oil smoke than fuel smoke. The ALDA has no effect on injection quantity until the turbo starts to build boost, it has no effect on injection quantity at idle and very little effect at low throttle positions.
