I have a predator 500 that has the starter clutch going bad. Well I go to pull the fly wheel and it won't budge. And I'm using the impact gun to let the vibrations help me free the flywheel but it's not enough. Any help on how to get this thing off is appreciated

 

At times it takes penetrant such as PB Blaster and heat from a propane torch around the crank shaft along with an impact gun to break these flywheels loose.
