It's getting hot here so the Coupe has been moved to storage for a while. Still battling the problem.
The carb is on its way back to Quadrajet Power again. I'm keeping fingers crossed Mark finds something.
Mark at Quadrajet Power gave me a great trade in on the carb I was working with that started this thread. It arrived about a month ago. Nicely recolored. Today I went on the Jefferson County Power Tour. I was able to give the new carb about a 100 mile burn in. The car is running great! Thanks Mark.
