FINALLY; it runs with some authortity!!!!

Bill did you calibrate the 02 sensor just a thought I don't no how it's done but your manual should tell you how it's done.
Mine only goes to 10.0, are you on a gasoline scale.

The power valve doesn't come into play till around 2500 rpm do inless its got a ripped diaphragm you could probably rule that out.

Which carb do you have on the car now bill?
Did you receive my email?
