The 'donut' connectors that came on a lot of our exhaust systems are notorious for leaking and causing popping. If that's the case, you can have NASA clean and adjust your carbs, and you will still have popping.

I was going to ask if you have any black, sooty stains on the exhaust system around those donut joints near the muffler, and then I read in your initial post 'black, sooty exhaust stains', so hmmm... maybe have a closer look at that.

Better systems use welded-on real flange joints instead of the donuts.

Just a thought.
