I have no rich running trouble now. That's for sure. I even added around 2 turns out on the mixture screws. Note that my fuel economy is about the same. So I gained very noticable power for no loss in economy.

I did all the tuning after weeks of research and discussions on other forums, lots of trial and error, lots of testing and hard pulls, etc.
