As far as I know, that saw is as it was when purchased new.. There has only been one person in that saw besides me.. Simonians from CA. as it was sent there because of the same " not running condition". While I was out of town... This time translates to the second time for a no run... Start up, run a bit, then quit. I find this whole episode disturbing at best.. (trying to be polite, not flat out vulgar). Like all of us , I want a quality, dependable tool.. Not a piece that we want to use, yet simply does not cooperate. The help and advise received here is the BEST and I thank everyone for their input.. Sadly, it's not over yet...... Good thing I have two other saws, and pretty well caught up feeding two stoves..
