Yeah ur one way is bad. Either clean it with degreaser or wd40 make sure its not seized. If seized just buy a new one, not to much. I will tell you this thoug traxxas is notourious for engine issues over anything else they make. If the engine dies and you want a direct drop in no modifications needed and also faste get the dynamite .19 onlt about $110. Best engine to drop in it and will last a long time compaired to a traxxas engine.
