RE: Can't Start my Lightning
First watch the tutorial videos for tuning and BREAKING IN THE CAR!!!!!on the redcat site or jubtoys site. Then break in the car (or that engine will never ever run to its full potential). You don't need it to run fast or performancy, just rich. Break it in before worrying about the high speed needle or anything. So just to get it started, mess with the idle screw. I'm sorry for that answer but with the details provided I cant really give anything better.
Note - The idle screw controls the opening in the carb when the engine is idling. AsUrcHobby said, turn the idle screw until your gap is 1 mm then try to start it from there.
