i understand that i have been racing for years but this is my first rossi motor and not to happy it went from running really good i was really happy with it and then it started all of this. it will not idle anymore. the other thing is that the glow might be going bad now that i think about it i dont think that i have changed the glow plug in it yet its the same one that came in it might be my prob with the idle prob. where has my head been??? i guess trying to get my pro series car ready
