Had hooked up the line that had come unhooked on the 576XP, and while I was hoping it would take care of it not wanting to idle down, I knew better, it didn't. I hooked it back up, and went out and cut with it for a few minutes. Once it was warmed up, it was just like it was before, wound right up still after letting of the throttle. So, I put it in my garage, and am gonna tear it down fully, and replace all of the gaskets, the crank seals, and all the lines just to be safe, and check everything else out while I'm in there. On the other hand, the MS460 I traded for that the guy accidentally ran with straight gas, has stepped up to fill it's spot for the time being. I've run a tank through the MS460, and it runs exceptional, very strong. I'll bet the guy that gave it away wouldn't have bought the replacement saw if he'd just put some mixed gas in it after it cooled down. I don't think it hurt it a bit...
