[8D]hi . so you tryed primming it and took out the glow plug and it glowed ? did you see any air in the fuel line ? replace the fuel line and glow plug and wen the glow plug is out see if you can see any nitro on the piston . check the carburator make sure it,s tite and check and see if it has any dirt in it . see if it,s getting enough throtle to start the engine . just lmk if it do,s not start . thank,s .
