Called local Stihl dealer today to get rings for a friends 361 and was informed that stihl doesn't sell just the rings I would have to buy a p&c kit for $265.I asked why you couldn't use a ball hone and just install new rings.His reply was that the coating on the cylinder was to thin.And this was a stihl elite dealer.Called another dealer 1/2 hour the other way he gave me a price said he'd have them in a couple days.He isn't even an elite dealer.Take a guess where i'll spend my money from now on?
