Before that, check the anti run-on solenoid. It is fitted to Weber carbs and, as the name suggests, cuts off fuel supply when the ignition is turned off to prevent dieseling.
I used to wire a hidden switch under the dashboard to this fellow - the symptoms are identical to those you describe - the car runs until the carb bowl is empty then stalls. As you crank it it fill again then runs out just as quickly.
