Okay, thanks for clearing that up for me. So im guessing once the nut comes off, the starter cup/cone comes off, are the 3 holes mentioned under this cup/cone? Also is there any specific way to hold the flywheel? The flywheel is missing a few fins and i can see obvious damange where someone has previously used a screw driver against the crankcase to try to immobilise it; with no success judging from what i can tell.
