Guys,
I might be losing my mind (perhaps reaching that age), but I can't seem to get my timing set for the life of me. Now, I've probably timed my A10 200 times and, at least three times correctly. Today, instead of using my traditional graticule stick down a plug hole I've actually got a dial indicator right on top of the piston. After several attmpts I'm not any to get closer than 70 to 100 thousandths. Usual deal: set the depth, adjust the points till the ciggy paper pulls out, smack the pinion home using a socket, tighten the pinion bolt, recheck BTDC. A couple of other things I do: wood wedge to create friction that stops points from sliding back down the slope when reaching "just open" position, wood wedge or screwdriver between points post and cam ring to hold points tight while tightening pinion bolt (while being real careful about hurting points or cam ring), solvent clean the pinion taper.
Even some consolation would help right now if this doesn't make sense to you, either. But, it HAS to be SOMETHING I'm doing wrong or missing. Just don't get it today, for some reason.
