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?
