No offence taken. Using a degree wheel, same one I've had for 20+ years, just not used all that much. Heads aren't on the motor, and the dial indicator plunger is directly into the lifter. As I mentioned before, 4 or 5 of the 9 keways on the crank sprocket won't go over the crank key, or bind up for some other reason...so after setting everything up as Yellow Rose posted, I just played with combinations (ignoring the dots on the sprocket) until I found one that lined up correctly. I'm thinking it was coincidence that it happened to be the 8 degree retarded slot.
