Hey i have a .15 engine on a traxxas sport and it cuts off when i pull the throttle full speed and the engine runs really hot. please help me with what to idle screws to turn and which way tighten/loosen

You are running lean on the high speed needle. Turn the HSN to factory settings and then turn the needle 1/8 increments clockwise until you get a good tune

remember turning the needle clockwise leans it out and turning counterclockwise richens the mixture.
