Choke driving me crazy!

There you go!
The cold engine will still want to be enriched at 68, but most of the time this can be overcome in the tune and with a minute or so of babysitting, as I call it; namely keeping the revs up or blipping the throttle.
Since you have a choke (I don't), you can use a little of it to get up on the fast idle cam, and then let her idle for a minute or two, then she might be good to go.
