Chainsaws

This is more of an FYI than a question; I bought a PP5020AV saw new in Oct of 2012. Used it half a dozen times over the course of the winter. I always use "Stabil" fuel stablizer, at the end of the season I drained the fuel and bar oil tanks and put it in the case for storage.. Last week I got it out to cut up a tree that had fallen, filled it with fresh fuel and bar oil. It started very hard and would idle but would sputter and quit past idle speed.. I thought maybe the fuel filter was clogged so I pulled the fuel line from the tank and proceeded to remove the filer when it was twisted and pulled from the line the inner wall of the line pulled out of the outer wall and stayed attached to the filter. The filter was pjust about plugged solid as well.  I  took it up the road to a small engine repair shop to get a new line and filter. Between myself and the owner of the shop we have more than 100 years of combined experience with gasoline engines from small stuff to Motorcycles and even race cars. Neither of us had ever seen this before ! Fuel line and filter replaced and the saw runs perfect again ! I have also had that fuel cap issue with a couple of saws including this one due to the ethanol !
