Since I am going to have to weld a sprocket, I can pretty much put anything I want on it. I might go with the #35 sprocket and wheel I already have. Then again I might go with the bike sprocket I also have one of those from the a rear coaster brake wheel. It is pretty big and with that high speed chain saw engine the bike might fly apart if I went that way. I guess I could pick up a #41 sprocket from a hardware store and have it welded to the centrifugal clutch of the chainsaw.
