Trouble with idle once warmed up , when cold runs

Probably really fat on the mix screws at idle. Set the idle screws when warmed up. You should have to give it some pedal to keep it running when cold because it should be really lean when cold without your choke.

Is any of the choke assembly still on the carb, possibly a fast idle cam coming into play?

Make sure your initial timing is set properly before setting the carb.
