Chainsaw Repair

I like to set saws on the rich side and you can hear them clear up when they get in the wood and start cutting.  Like a blubbering sound out of the wood aka 4 stroking and clear up and sound like a mad hornet in the cut.  No certain rpm just by ear.

 I  use a tach to check saws settings with and make sure my ears are not way off and get one set to lean when I am pushing the limits looking for the quickest cut times (when goofing around testing stuff).  If you do like above I dont think you could ever go wrong.
