An impact gun works best, if you don't have one you can make a strap wrench out of some rope and make a half hitch around the flywheel and make a loop then use a big wrench or pipe or something to hold it, the more you tighten the tighter it gets. (also good for removing oil filters). Another way with small engines is to remove the spark plug, turn the engine until the piston is down in the cylinder then feed in a bunch of rope to fill the cylinder with it. That will lock the engine so you can tighten that nut. I prefer the impact or half hitch method.
