I pulled off the flywheel for a tune up. I found the cam shaft key had come out. the slot is 1/2 on the cam shaft and 1/2 on cam. They are not in alignment so the key will not fit. How do I align the slots.
Use a wee bit of fine valve grinding compound to clean up the tapers ( flywheel and crankshaft ) for a good fit.----Do this before fitting the new key.
