The number you posted looks like a Sears Craftsman part number from the engine. From a way earlier post: # 143-584012 crosses to techumseh h35.

We're having a hard time understanding what you mean by
some metal pieces came out of where the chain spins
.

Are you talking about the clutch that is on the engine, or the rear sprocket?
