I agree with Brian, don`t take this lying down. In the vein that John is thinking, what about small claims court? You might have a slam dunk for a little of your time and $10 - $15 if you can get some evidence from Stihl showing that the carbs are the same in Oregon and Minnesota, or if the defendent loses by not showing up. I`d wave this idea in their faces because in many cases of a few hundred dollars, even if the charges are legitimate, a small business cannot afford the time in court to defend themselves. Ordinarily I would not encourage you to do this but those guys are taking you to the cleaners while their tech learns how to do his job. I would further insist that you get your old parts back, you own them, and you may need them or they may be saleable. of course I don`t know what your personality is, you actually seem like too nice a guy, but I would try to muster whatever it takes to make a few demands that they fix your saw free of charge and don`t take no for an answer. Besides, are you worried about ruffling their feathers? What are the chances you will ever deal with them again? Hang in there Timberturner, the battles worth winning usually aren`t easy. Russ
