I have a Briggs and Stratton engine on my Weed Eater 22” lawn mower. The flywheel nut will NOT come off. I have seen plenty of videos on how to get it out but all of those flywheels stopped in the opposite direction. My flywheel will freely spin in either direction. I’ve had a second pair of hands to help me steady it but it’s still too seized. Is this screw something that I can safely drill out?
