Harmonic balancer is off the old engine put on the reman, Running carb not fi. By timing light the single mark on the balancer is off the scale by quite a bit toward the passenger side. Runs fairly well. electrictronic ignition with vacum advance. Sticker calls for 0 degrees but to get to that I would have to turn the distributer halfway around or more. Im thinking the harmonic balancer mark is not right for this engine or the person who set it up didnt top dead center it before dropping the distributer in. Far as I can see there is only one mark on the balancer no dergree marks. any ideas how to set this up so I can check the timing with the timing light?
