Does anyone know where I can purchase that little set screw that you remove when you adjust the flower nut on the clutch? I live in a rural area and have checked three local stores with no luck. The auto supply had one the same diameter, but longer. I have also checked several websites with parts and I haven't seen a clutch listed, let alone the screw. If anyone has any idea about where I could get one or more, it would be very appreciated.
