Harmonic balancer

I mean you needed the balancer when you degreed the camshaft. You would have found the error then and remarked the balancer.

No, you cannot just arbitrarily remark the balancer. You need to find true TDC with a piston stop first. Then you will have a correct reference to make a new mark.

Never in my life have I had a balancer on when degreeing a camshaft , always checked it for true at top dead center afterward tho-----------??
Most of the time I have an 18 time national record holder check my work !~
