I can not get the nut off before you can pull the mag/flywheel, and no matter what I do it won't lossen so I wonder if it's reverse thread because otherwise idk. my timing chain broke so that's why I need to pull it, and I got the tool for that.

 

Afraid I can't help with that but would advise you to get a workshop manual for any major work on an engine. You need the torque setting for that nut, when it goes back, anyway, too slack and the flywheel will loosen off, too tight and you will never get the flywheel off with the special tool, as the flywheel gets forced so tight on the taper, it locks.
