This week I bought a new bar and two new chains for my chainsaw (Stihl MS260) The current bar/chain size is 16? .325, .063, 62 teeth. I thought that it was a 67 tooth chain, and ordered that. When I got it I realized my mistake, but decided I would prefer to switch to the 67 tooth size (it makes no sense how two chains of entirely different lengths can both be called 16" but that's another discussion). I tried to out the new chain/bar on and found it simply won't work. The bar will fit, but it't not possible to tighten the chain enough to make it work. This bar is supposed to work with my chainsaw, but unless I'm missing something obvious, it doesn't. If the post on the tensioner was in a different location, it would work. It would also work if I drilled a new hole in the bar, but I'd prefer not to do that. Anyone know, or have an idea, as to why I can't get this to work?
