Hi Don, I already have the MX service manual and, while it is useful for disassembly and assembly there isn't much help in troubleshooting. So I was hoping some one would tell me, "you tale off the bottom plate, ajust the whatsit and put a smudge of grease on the thingme and it will work..." or at lease suggest the first things to look at. I am confident I can disassemble, less confident that I can reassemble, so want to do only the minimum! Grant
