I am not going to use the the Crank from my old power head since it clearly shows a flaw on one of the journals.
I purchase a replacement crank from Ebay not knowing I will pick up an entire engine so I now have two crank on going back on Ebay.
I have since clean up my crank and lube it with 2 stroke oil and wrap it in plastic until I am ready for it.
Here are the before and after photos (crank inserted on the mid-section during the clean up)
Old crank now obsolete see #3 ?

Crank from ebay not cleaned.
