Turns out the auxair valve and control pressure regulator relay had an iffy ground. The engine stayed on full rich. I screwed it down to the mounting plate and all is well.

As I remember it, those grounds are just for the heaters, which are in there to provide a quicker "warmed up" state.

The engine won't "stay full rich" because even without the heaters, the AAV and CPR will stabilize air and fuel mix to "warm-normal values" due to ambient engine heat.

It just takes a little longer, depending on outside temps. In warm weather, the heaters hardly come into play at all, IMO.
