I found on my O-360 F1A6 (Cutlass)Lycoming that one prop mounting lug was a slightly larger diameter than all the others thus making relocation of the prop impossible. This engine is counterweighted and maybe the lug is oversized to ensure the prop always goes in the most balanced position. It was annoying because the blade finished up low down where you couldn't pull it through in the event of a flat battery.
