I have talked to local stihl dealer and he says they are having some problems but that he is not sure exactly what they are at this point. I have had 6 261's with the crank wore where the clutch bearing rides on it and a couple 362's with the same problem along with a 362 that the big end rod bearing failed on.362 with rod bearing failure has a perfect piston and cylinder. I dug the 362 out from under the bench to take a picture. it has been hanging around the shop for 6 months and decided to add it in to my questions about the 261. Anyone else seeing these issues or do I pass these all off as isolated cases of operator error.
