It is bad. I'm not sure what the diameter is but 3 inches should be about 50 to 55 degrees off if my guess is in the ballpark.

This is what I found. The blue dot is the TDC mark. It sure doesn’t match the other picture.

Yes - if you are looking at the damper and pointer from the front as Ted said. stbart (3/25/2022)
I followed the method Ted suggested. I used a straightedge across the valves, ensuring that that are level, and the timing pointer is 3 inches from the TDC mark on the damper to the left, or ATDC. Is is safe to say that the damper is bad?

One is between 9 & 10; the other is closer to 12. I don't see how turning them over/looking at them from another angle will put the two marks in the same location.

The damper is all packaged up and on its way to The Damper Dudes!
Thank you everyone for the tips and comments.
I will have more questions soon as I have a few more things I am fixing before the summer season.

Once you get that damper back from the rebuilder, I will suggest that you scribe or cut a mark across the pulley groove parallel with the ‘TDC’ mark on the damper ring so that you can always verify that the damper ring has not slipped. This is just good insurance for checking that the damper ring is staying in place as time goes on.
