At this point, if you can, I would run it again for a tankful just to get rid of any crud that may have formed inside it. At the end of the run, while still running and being careful of the prop, remove the fuel line (can be removed at the tank too) and let it run til it quits. Reconnect the glow battery and try to restart for a bit to make sure out of fuel.

Can start here if engine can not be run.
Put after-run oil in open carb (liberal application) and turn engine over by hand for several revolutions to distribute oil thru engine. Remove glow plug and add a little oil to cylinder and turn engine over another turn or 2. Reinstall glow plug and place engine inside baggie to keep clean.

That should do it
