Chainsaw Repair

I feel that on short bars you can run a 7 or 8 and like was said earlier you won't notice that much of a difference. You will gain a little more chain speed. If you are running long bars I would stick with a 7 pin slower chain speed but more torque to pull it threw the cut. Based on a stock saw, it all changes as mods start to happen.

As I tried to say, just try the options yourself - rims are cheap, at least in those sizes.
