    I tried an 8 tooth sprocket on my MS 660

    Tested on a newer Stihl MS 660 with a 25" bar There is chainsaw fanatic in Portland OR that sells alot of Hot Saws on Ebay, he knows his stuff better than anyone I know, he recommends going to a bigger sprocket rather then increasing HP, so I had to try it. I ended up going back to a 7 tooth...
