I don't understand what this metal rod is. Can you post a picture of it please? I can't even find a clutch housing - the whole clutch is in the open air, and rotates with the output shaft. Of course the clutch has to be removed from the crankshaft extension (what Briggs & Stratton call the "Power Take Off", and I call the output shaft) before the timing cover can be slid down the shaft and removed. Do you mean how do you remove the clutch from the engine's output shaft?
