Where's the Wow?

I used the 10 degree BTDC mark on timing cover and I have degree tape on the balancer. So it hit the stop at 40 BTDC on the damper one way and 20 ATDC the other way at the same spot on the cover. If I need to use the degree wheel instead I will do that tomorrow.

You do if you want it right. Degree wheel and dial indicator. Not trying to be smart, but how many times do you want to do this? You need to be SURE. Know what I mean, Vern?
