Usually when the engine dies after removing the glow starter, it means the engine is running too rich. You probably removed the glow starter soon after starting, so you were probably idling. You should try leaning your low end some just to keep it running. Once it will run after removing the glow starter, get the high end set right. This is after break-in, of course. During break-in, you want to be running pretty rich, but not as rich as you're currently running.
