pulley, you can feel two or three more pointers out of sight. These would be
5, 10 and 15 degrees, I believe. Haynes says 10 degrees is correct for the
69. I scribed a mark back on the cover in line where I felt the 10 degree
pointer to be, to use for reference. (On this subject, is there a
possibility that the balancer has been replaced by one with a bigger
