While removing the clutch cover plate, the slotted screw that goes into center of drive gear (right of clutch ), fell out.
It looks as if some of the threads, maybe 3/16" have worn off the end of the screw. I can screw it back in, no problem, but not sure how well it is seating with fewer threads. Does anyone know where I could purchase this screw, have looked around and can't seem to find it. I have also looked for pictures of the screw that would show whether or not it should be threaded all the way down but have not found any. Norman thinks that it probably did have threads all the way but not 100% sure.
Anyone know for sure if it should be threaded all the way and if so where I might get a replacement?.
