Cam degreeing help me understand!

If you look at post 155 I was able to get the cam set up very close to the cam card by advancing the crank gear +4 degrees. The
cam timing was off slightly but is probably within margin of error. Tomorrow I will try that set-up again and report back.
Then I will either need to live with it that way or purchase an 8 way timing set.
The offset keyway being ground wrong makes sense but man it's hard to imagine an extra 6 degrees from that little hunk of ****.
Maybe I can try it at the crank.
