1996 blaster, is the flywheel nut reverse threads?

your best bet is an impact gun....what i did was put a wrench on the nut and wacked the wrech with a hammer to break it loose.....and you will need a flywheel puller to get the fly wheel off
 
if you dont have a flywheel holding tool. then you could use a large set of channel locks. i have a pair at work that i have used before. but just like yb200 said you will need a flywheel puller to get it off.
