Madsen's for 3/8 9T-10T. $21-$23.Who's the vendor?
I haven't found any, but would like to try one. Running an Oregon Power match plus bar from a standard stihl that we milled out to fit (30" .050x.375) the 084. Using an 8 tooth, but I know the saw would handle a 9, maybe a 10. Only problem with going bigger might be that the heel of the bar might not be big enough for the bigger sprocket. Back to the milling machine????
