Still stalling after carb rebuild. ???

So she was stalling before the rebuild? Are you sure you have a fuel problem, done all the default troubleshooting? Good fuel pressure? Consistent spark? The running cycle getting progressively shorter as the car warms up? All stock? Set the idle screws at 1 to 1-1/2 and 1-leave. Check the static timing(TDC)
Back off to 1-1/2 on all three from tightest point? Yes, as she warms up at one point you hear hear the engine start to slow and about 15 sec later she stalls.
