After talking with several people here locally today, I'm wondering if just trying to match the balance between the old and new flywheels will even work. They are of the opinion that the whole rotating assembly needs to be balanced as a unit. If the new wheel is drilled like the old, just being off a small amount will affect balance and cause a vibration. I'm starting to think maybe I should just keep the old alum flywheel on this application, it might be more trouble than it's worth.
