Husky 440 has a racing idle now.

[fireheart]

I've done it now. It's screaming. I was trying to adjust the carb because the saw won't start when hot. I decided to follow a guy on Youtube. He said to turn down all three L, H and T screw clockwise. Turns out doing this to the T screw sped up the idle so much it's racing. I backed down turn after turn on the T screw and the idle does not slow down at all. is it possible I unscrewed the t screw all the way out?
