How long does it take to stall? Is it rather quick? Possibly a vac. leak? I also agree that it could be timing as well. Or maybe the choke flap is set right, but maybe the high idle is not?

Well, if it was a fuel starvation problem you'd have more of an issue when driving, especially on acceleration. For the most part there is plenty of fuel in the carburetor bowl to keep it running at idle as long as there's even a trickle coming from the pump to replentish it.

Best thing to do if you're taking it back to the mechanic is let them have it overnight so they can get it to reproduce the problem when it's stone cold. Then they can see it first hand.

i kind of had of had the same problem with my 79 403 a few years back would run fine going down the road and when first cold but then would stall out at idle, it ended up being a bad EGR valve.

You really should go through the diagnosis in the service manual.  It could be a number of things, some of which have been mentioned.  But, with this type of problem it's really hard for someone to tell you what's wrong from their computer screen.
