Stahl issues: Carb or Timing?

Ok, so I've had a few recent threads about my recent issues with my 318. Up to this point, I have had the carb rebuilt, replaced the coil, and upgraded the points to a Pertronix kit.
I have had a few issues up to this point:
1) The timing was 10* retarded and it was hard to start and missed under hard acceleration.
Action: Adjusted timing to 5* advanced.
2) Fixed the timing, and then it would start great and run great until warm and then the idle would drop and stahl out.
Action: Adjusted fuel mixture screws to raise curb idle.
and now....
3) Car starts awesome, runs great, until its warm and then it will stahl out when driving while pulling up to a stop sign or into a parking spot. It has left me setting 3 times just in one trip today.

With this being said, does it appear to be more of a timing issue, carb setting issue, or idle issue?

My choke seems to be working fine as the butterfly opens normally as it warms up.
