I'm at a loss here. I'm running 17/93 with no motor timing and a tekin rs with no timing advance. been debating on switching to 550 for this very reason. (overheating) waiting on tekin 4-pole motor right now as I am not a cc fan. don't like run times with 550's and don't need any more power.....but its just too hot right now. drivetrain is free...no binding... any thoughts?
