I finally had enough with the rattly motor. Convinced it was a cam chain guide gone the way of the dodo, I pulled the motor and found the following:
It sure is easy to push now!
I really can't find anything wrong. When my old Seca turbo cracked it's front cam chain guide, I knew right away when I pulled the cam cover that the chain had been buzzing away at the top because of the fresh rub marks, but there is no evidence whatsoever that the chain has been rubbing anywhere. The front guide looks ok (I will replace it anyway) and the back guide has some light tracking, but no real signs of distress. Kind of bummed, but at least I know nothing major is failing, and the motor really needed painting anyway, so I'll order up the new gaskets and button her back up. Rotten outcome after 4 hours work in the heat and rain. Notice my lovely work surface. Ah well...
