To help detail the problem I took a movie of the tach while in NY traffic. You can see when I move the car slowly then push in the clutch and the rpms fall. It usually hangs at 1000 rpm for a few seconds then falls to 750 or so. Sometimes it falls below 1000 then creeps back up then 4 or 5 seconds later falls to 750 or so again. Note when you simply rev the motor with engaging the clutch it falls fine back to idle. You can see each of these instances in the movie.
I will post it shortly.
By the way I left you a message yesterday.
Thanks for your assistance.

I had the same issue. I took some measurements between the throttle arm and the area where the stop screw is. I then by feel backed out the set screw until the throttle plate hit the TB, then put the screw back in enough to prevent the plate from hitting. The idle problem went totally away, works really good. I measured a 0.029 gap between the arm and the housing with the stop screw in the as delivered condition and about 0.010 after my adjustment. given the production tolerances here this will have to be done by feel, but as long as you get it where the throttle plate doesn't hit the inside of the TB and is a bit more closed it should help. As I said, it completely fixed my issue which was identical to what you described.
It is critically important you have the throttle blade as perfectly centered as possible when you initially put this thing together, that's what the deal with the paper between the blade and the TB when you tighten the screws is all about.
