Relatively new here, and have a question. I have an MS270 that is about 7 years old. It has been a great saw, and I've not really ever had to do anything to it, other than keep gas and oil in it, and the chain sharp.
I've recently started to go over it...new air filter, new plug, carb tune up, new bar, new sprocket, new chain, etc.
The first time I went to the local stihl guy, his mechanic gave me the wrong part number for my sprocket. I took it back, told him it was wrong, and he went to find the right one for me. He came back with an 8 tooth sprocket. OEM is 7 tooth, and the new MS270 he had on display was wearing a 7 tooth as well. He told me i would just pick up a little bit of chain speed with the 8 tooth. Is this accurate? If so, why is stihl still putting the 7 tooth on as original equipment?
thanks,
