It made a clunk and stopped. Now the atarter just spins and the mottor doesnt kick over like it did when the one way was bad. I think the one way broke again.

I replaced the one way starter clutch on the 03 400ex I just picked up and got it running. I took it around the house and then brought it into the garage went back about 10 minutes later and started it and it idled for about 3 minutes and made a clunk and shut off. Now its doing the same thing as before the one way clutch was replaced. What would have made it do that? Also i dont know what all has been done to the motor. I was told it was bored and piston shaved. I do nopw it sounds like the valves need adjusting. Any ideas on why the one way clutch would brake like that?
