RE: "Don't forget Stihl"
Well i went to the stihl site and searched and came up with nothing on the FS-74.So i guess youd have to call a service center.Im sure i read it there but maybe they took it off there site.I have one thats 25.4 and its supposed to come off of that saw.I also have a SG-75 thats supose to be 25.4.
