i got a nitro car brand new has a 21CXP - .21 Engine if that matters with a pull start i can't get it to start up i even tried a new glow plug its not flooded thats the first thing i checked the only problem i can think of is I'm using a AA battery glow plug starter and i put a glow plug on the end of it and it didnt glow so maybe its not getting enough juice i even tried brand new battery are these sufficient for starting this type of engine?
