That sounds more like the STARTER CLUTCH, I would take the side back off and check the starter clutch.

finally got around to pulling motor apart today .... still running ... still knocking .... replaced starter clutch ....reassembled and fired it up ....  still knocking. did find 2 small ball bearings in the oil on start clutch side ... way to small for crank bearings ... maybe ...maybe the size of really worn cam bearings but mine are both still there lol ..... only thing left is to tear it completely down one weekend and see what i have |
