I ended up sending the carb bodies out to Tom Bryant in Maine who replaces the brass with delrin for a decent price. I heard good things about his work. I think any modern option whether it be PTFE, oilite bronze, or delrin would be an improvement over the stock setup.

I'll post some pictures when I get them back.

I wish I had a drill press and reamers or I could be doing this work at home.
