This engine is 32 years old and never been run. I started a break in today, but it will not keep running, unless the glow plug is connected to the battery. When I take the glow plug power off, the engine runs for a couple of seconds and quites. Put the glow plug power back on, it start right up and will continue to run until you take the power of the glow plug. I've tried running it throught a full tank of fuel, with glow plug connected, but it still quites when the power is disconnected from the glow plug.
Any ideas??
