I believe it was a port for the second EGR valve. After replacing the car ran better. Stopped the stalling and difficult starting but continues with the lean acting condition. Float has no adjustment that I could find. Was not filled with fuel, which if I remember right would have just caused a rich or flooding condition and the internal fuel filter was clean.
Lean condition seems less as the car heats up.
Occurs through all speed ranges and in general is a pain in the neck to drive and repair. I never thought I would have to work on a carburetor again in my life. But she really can not afford a new car. Oh well once a dad always a dad. Thanks for any tips.
