Hello, i have acquired a cf500 that doesnt start. I think i have traced the problem to the woodruff key having moved on the flywheel as the tdc mark on the flywheel is way out when the piston is at TDC. I bought the correct puller but , my god the flywheel just doesnt want to budge, plenty of heat , the right too and i am stressing about putting so much force that it destroys the end of the craknshaft. Any advice??
