    Loud Bang/Mini Explosion, Now it Won't Start

    I'd pull the flywheel first and look at your flywheel key .... Sheering it in half will throw the timing off and backfire a loud explosion. Throwing a rod would have ," I'm most cases spray your legs with oil and make a oil mess". And you say you get back home and it pull starts fine but...
