Most craftsman chain saw clutches are left hand thread. You can try a couple of things. In most cases you need to put a cylinder stop in to limit crank travel, then take of the clutch with tools offered by Baileys, or take a 3/8" flat bottom punch a carefull hit the clutch drive shoe frame. this will hope fully spin it off.
I have one apart right now on the bench. My problem is getting the oil pump worm drive off.
