Not a good day. Just went to do a little clean up after some rain, and after a few cuts the 5100 is not showing any compression. I pulled the muffler, and the piston has some pretty bad scoring. It looks like there is no ring(is that possible?). From what little I could see the cylinder wall looks ok, but dont they usually go together? I just called my dealer, and yes its 8 months out of warrenty. $180 for a new piston and cylinder sounds high. They are also going to check the gas, but it was fresh, and just mixed, tuned by the dealer less than a year ago. It has been a great saw.......up to this point.
