Thanks for all the great replies. Benzmac, to answer your question, I thought that I had seen a post where it was highly recommended to replace one of these chains indicating that they were bad about breaking. Maybe the message I saw pertained to a later, two cam 300E.
I won't argue, there's more than one of you telling me this chain is as rugged as an anvil.
As always, thanks for the great information. Looks like I will reclaim a Saturday that I was going to give to the car. Maybe there's a big Black Bass in my Pond that needs catching.........
