Hmm.. From what I have read I want 10 cam / rotor degrees BTDC not 10 balancer degrees. The balacer degrees on the tape, as I understand it, are actually not 10 degrees rotation of the balancer but 10 degrees rotation of the cam and 20 degrees of the balacer.
10 degrees at the balancer would be 5 degrees BTDC for the cam / rotor...

My balancer has chipped paint for the 2 inches around the TDC machined marking. Any paint/tape or other on the balancer would be invisible.

Any one know for sure if it is 10 BTDC cam/rotor/balancer?
