Looking at this again. If you have a 930/63, 62, or 65. the spec is 31 degrees +/- 4 dgrees BTDC @ 4000 RPM. Vacuum disconnected for checking, and for adjustment it is 5 degrees +/- 1 degree ATDC @ 1000RPM +/- 50 rpm Vacuum hose connected. OK if that is your engine I see what you are talking about 5d ATDC would suck!
