Hello im just about done with a 211c that i dropped and had a big limb fall on. I got all the parts swapped and went bar shopping. The two dealers i stoped at didn't have a bar. The one had a Oregon bar and said it would match up so i said sure being a saw novice. Well the bar is not same i tried using the new bar with a stihl chain and it wouldn't work the chain was to short. So i looked and the bars are different but the chain size on the bars are the same. So im kinda confused.
