I was a little shocked (or I wish the saw was) when my relatively new Stihl 390 stopped working yesterday. I hit the compression button, pulled a few times, got the first kick in, then moved the start button up. It started up as usual then sputtered out. I hurt my elbow trying to start it afterwards. Gave it a day to sit thinking it was flooded. Checked the plug for spark, and no spark. I guess it will be under warranty so I am taking it back. Any ideas on what it is? Ignition or something. I am a little surprised it died this soon, about 9 months.
