The flywheel has those two studs with the starter pulley hooks on them. How are they removed? Are the pins pushed in? Threaded in? Etc....
I usually have to heat the flywheel with a propane torch and gently pry with a screwdriver to get it off. Also, you can put a nut on the end of the crank and tap with a hammer while prying.
You can drill through to the pins from the back side, then use a piece of hard wire and a hammer to tap them out.
