Chainsaw Repair

Art something I noticed on the one the guy brought to the house. They are coming with 1 set of rollers and they are a different size then I used. Mine came with 3 sets of rollers straight from Sweden.

While sandusky was here we took a stock CL chain and then used his square atop filed chain and he was knocking off 3 tenths on his chain in softwood cuts.   We didnt write anything down so I cant get any deeper with info.
I do know he uses a different file and holds the file on the guide different then I do. So it seems a lot of factors come into play, just like user input on hand filing.
