I have used this technique on some 9hp Wisconsin engines and other small engines.Do NOT strike the fly wheel directally, they are made of cast iron, they can develop hair line cracks which when running can cause pieces to fly off at high speed.I totally know how hard it can be to remove the fly wheel, they can be evil things! good luck.</blockquote>
