RE: Stihl fs74 cc?
Man, did you take the nut off??
I usually just wedge two screwdrivers in under the flywheel however possible, screw the nut on the crank until it is flush, and then give the end of the crank a hit with a hammer. They pop right off, usually with no heat. I can't even remember the last time I had to heat one to get it off....
