Does it turn over all-right?

To run it needs fuel and a well glowing glowplug. Even "poor" plugs usually work while the power is on, but will shut down when the power is removed (assuming it isn't broken but just lost its catalytic ability). The new battery driven glowdrivers have to be absolutely fully charged to provide enough juice to fire up an engine that is flooded.
You can prime the side of the piston with the muffler off, and no fuel connected, just to see that you get it to fire. Then repeat with the tank hooked up (you can use an external fresh one if needed) and it should keep running.
