Do not use that puller. It may damage the flywheel. Make yourself a knocker. Find a couple of nuts and short bolt, the shorter the better, same thread as the shaft. Run a nut up on the bolt, then the second one on only a couple of turns, then run the first nut back down to jam against the second one. You just made a special tool.
To use, thread the knocker onto the shaft, hand tight. Lift or gently pry upward on the flywheel and give the knocker a rap or two with a hammer. Put away the sledge, only 16 oz MAX hammer. It is the shock that does it, not the bash.
Works with lawn mowers and chainsaws also.
