MARKED FOR REPEATABILITY
I always mark the flywheel when I’m done balancing so the customer will install it in the exact same spot as where I balanced it. I always shift it full right on the slop in the mounting bolts, opposite crankshaft rotation. Testing with a counterweighted flywheel shows the balance can change many grams when turned the other direction, depending on the bolt hole clearance.
