Brand New reciprocating shaft & a new bushing pressed into the reciprocating counter weight. The engine shop didn't even charge me for the 5 min. job.

New shaft, shown above, in position w/new bushing on the counterweight below.
View attachment 233807Had to sit the engine sideways to get the flat tappets & pushrods to stay in place while I put the camshaft back in. Put the two timing dots together.

I still see some of my cheap Autozone deglaze stones showing some crosshatching.

Other than getting a new governor gear (plastic), & many other small things you have to remember, I put it all back together today. Poured some 15w-40 Super Tech HDEO FS in which takes an oddball 1.9 quarts I had to measure out. Fired it up & took it around the yard & no more engine knock! Success! Now I know to not to put parts that are out of specification in during rebuild. Some parts may get away with while other cause a knock.

Here's the second UOA I did on this engine while it was knocking. Hopefully, metals will come down now after an oil change or two.
