Hi had to remove flywheel as the cone was seized , after some heat and inox finally got it off. The shaft was badly corroded ,when checking the thread on the shaft it was a uns thread . a bit unusual . I welded the shaft and brought it back to specs. The shaft screws into the governing cam and on the engine side of the cam is a eccentric hole with 2 lobes . there is nothing inside this section, should there be something there as it makes no sense at present. If anybody has a picture of that area I would appreciate it, so I can get this engine finished. Thanks Rudy
