I have did my best to isolate the problem. In order to eliminate a variable I removed the front derailleur completely. Since the problem continues even without a front derailleur at least I have one less thing to consider. I’m thinking about taking the large chain ring off if it gives me a better vantage point to examine. It is original to the bike so I don’t know if it’s simply wear to the ring. I’ll update with more info as it comes.

Thank you for trying to help with this.
