1st thing-Charge up glow starter, starter box batts-if you have them.. Make sure its all funnly charged. Put the piston at Bottom dead centre/make sure the flywheel moves. Maybe try new glowplug and see if that helps.. make sure fuel is getting into the carb and your idle screw is in a bit more. Heat the engine case up then try again.. in short bursts..Was it running ok when it did start. I.E. Solid idle ect? as it could be too rich, too lean, idle not gap not large enough.. soo many variables..
