Caution: Prying on the magnet can actually bend the crankshaft. The shaft is only about 5/16" in diameter where the magnet rides and prying it, applying too much pressure on one side can compromise the crankshaft. Use a puller, or the faucet tool, to assure even pressure. There is also a woodruff key that can sometimes complicate removal of the magnet. Use care and patients and don't damage the crank seal behind the magnet. Also mark the magnet, inside-outside, so it goes back on the way it came off.

I don't know if the other engines will do that cause I mark them before I take them off this one I forgot to mark. I didn't think it would matter on the one I put on backwards but it matters at least this one don't like being on backwards.
Yes if you flip that magnet around the motor will not run.
Ace is the place I did not know they had Ace in Ecuador
