Engine stalls upon braking

Do you have to crank-n-crank with the throttle open to restart? That's flooding.
If you have to give it a few pumps to help start, that's starving for fuel.

If the gap at the points is too small, you won't be opening the points to make spark when you take your foot off the gas and the
vacuum canister goes full advance.
Try opening the point gap a smidgen.
