Resurrecting an old thread on hope of some answer. I had purchased a 58 CD way back. It was run a few tanks on bench and then went into storage and that too without proper lube up. Recent too out and realised the bearings were all notchy. So changed all the bearings. However on assembly I notice (and hear) a very distinct gear noise. I don't recall this noise in the engine before. I also checked my NIB 91CD and do not hear the noise..
Should I run the engine as is? Or is there something not matching up that needs correction?
