When my then new to me RV-9A had high EGT, I called the factory and told them what was going on. They recommended a carb that I bought from Aircraft Spruce, and I think it was an exchange. That carb was richer than the previous carb, and it almost did what I wanted. The factory suggested I send that carb back to them for adjustment. I did, they did, and all was well.
I also asked about drilling out the jet, and I found out that is a really, really bad idea.
