Wheres the timing mark?

In your pic with the tape on the balancer and the 2 black marks. The factory mark(in white) is right in the middle as it should be, BUT it's not lined up with TDC marks on timing cover?? Did you rotate to take pic?
Take a marker and draw a straight line across the inner and outer rings. That will show if it slips. Same theory as racers marking rims and tires.
