I had the same problem with my car when I first put it on the road. It turns out that the Idle jet was too small (or blocked) and I could not get it to idle slow enough so my engine was using the main jet for Idling.( Causing a higher engine idle speed) When I braked the gas would flow forward in the carb, lowering the fuel level at the jets and the engine would stall. Fixing the idle jet solved the problem. Hope this helps.
