I in no way disagree with you... but I ain't got no MSD kit.
It got lost somewhere between Danbury, the original owner and me. I was putting that off until I had the parts in hand. (I wish I had the 3000 rev limiter chip, too...)
Let me see if the local shop has a spring kit.
As for the idlers, a turn and a half out was clearly off - I tried taking them out a ways to see if there was a vacuum peak further up the scale and the result was pretty bad (don't recall the specifics). I can try it again, though.
