The only thing I have noticed when my one way bearing went out was when I shut the machine off, I could still hear the cent. clutch winding down for several seconds until it cane to a stop, and then made a click noise. Does yours do this? The other symptom is going down a steeper hill. If your in gear, and rolling down the hill, it will almost be as if you are in neutral and roll freely, but when you hit the gas at the bottom of the hill, the clutch engages. I dont recall any problems intermitently when the engine is running though.
