I've had a couple pretty good unrestored carbs that showed signs of black paint inside the bowl and throat. I used Aero Gloss to paint mine inside and out, and after 10 years the paint inside the bowl is mostly gone. At about 5 years I could see some has slowly disappeared, but it definately doesn't flake off and cause problems.
If I hadn't use the 10% crap gas for a few years the paint might still be good inside.
