If the motor has the original fuel and air lines going to the connector, the lines will get brittle and crack over time causing a leak in the air line. If the airline is leaking, it can’t pressurise the tank and the motor will starve for fuel. Also, if the tank is almost empty, it can take a little while for the air pressure to build up and pumping the thumb button on the tank a few times will be necessary to keep the motor running until there is enough air pressure to deliver the fuel to the carb. After running the motor for a short while, you should hear the sound of pressurised air escaping when you crack open the tanks filler cap.
