Stihl 056 AV electronic for 50 EUR (no chain break). The guy said it has a problem with dying when hot. They changed Bosh ignition system a few years back and still has a problem. I hope its just the amount of dirt and baked oil causing to overheat. Cilinder and piston are like new. I gave it a good clean (12 hours of labor) and ended up like this... did a quick test and it runs great. Will have to wait until a get some big wood to crank er up and see if we still have a problem.
