Plugs are new Bosch, and this is an ROW SC, which doesn't have vacuum retard.
Follow up:
Allrighty, I went by there on my way home from work and had my local guy adjust the mixture. It was lean. The idle immediately smoothed out and raised a bit when he richened it. He checked my timing too. It was a "hair below 30 BTDC @ 6,000 RPM). It was noticeably more peppy on the way home. I'll have to wait until tomorrow when it stone cold to test the cold start.
I also sprayed carb cleaner in various typical problem areas of the engine. There were no fluctuations in idle anywhere, so it appears that I don't have any vacuum leaks.
So if I'm still having cold running issues, I'm guessing it's the WUR. And at $500, I'll just be dealing with a rough cold start and probably NOT buying a new WUR.
