I have decided that tuning a moped like my Puch E 50 is actually A Fine Art. It isn't something that is easy to learn but so satisfying when you finely accomplish it.
I Got mine running right at last, hitting 30MPH at WOT and good power on hills.
Everything stock except the after market Air Filter and a #74 Jet. in the 12 MM Bing.
Thanks to all of you who helped and those who posted great information on Wiki.
