Dave,

I am not sure but, I was under the impression that dwell measured the length of
time (measured in degrees of arc) that the points were open.  This is at least
partly dependent on the gap of the points.

Since electronic ignitions don't have points that open and close the dwell
measurement is not used.  I looked in some of my car manuals - the ones that had
electronic ignition didn't give a spec.  The ones using points all gave a spec.

I would try to get the richness tamed and check out the coil.

Good Luck.
