A few months ago I posted this question regarding an ill running 036 Pro.
Problems with Stihl 036 Pro, please help
I really appreciate the advice I got here. I followed the recommendations to replace the sealing plate. That did not solve the problem. At that point my buddy that ownes the saw wanted to take it to his Stihl dealer so I never got around to changing the welch plug.
The dealer worked on it and told my buddy the "seals" in the carb were bad from not running the carb empty after the last time it was used. So they sold him a new carb and charged him $160 including labor. Saw ran great with the new carb.
This is my question: Is the dealer hosing him by selling a new carb? Sounds to me like they couldn't figure it out and sold him a new one to get it off their bench and save labor time. I have owned and worked on many 2 and 4 stroke engines and know letting fuel sit in the carb leads to problems most notably varnish build up but have never heard of the fuel eating seals. Why didn't the dealer just replace the bad gaskets then?
Just wondering what you all think. Thanks for any opinions.
