Still stalling after carb rebuild. ???

Almost sounds like something electrical is heating up and failing. Have you checked that it's still getting fire when it quits?
True that. When it stalls you have to do some diagnosis. Does it have spark/ Does it have fuel/ Does it have compression? Spark and fuel can go away. rarely does compression go away unless AJ has been under the hood adjusting valves. :poke::poke::rofl:
