DVW, today I am going to do the spring test where I watch the metering rod assembly to see how it reacts with a little throttle. I do not think it is opening too soon though. However, I am not convinced that I have the right springs so I am going to monitor the system for a few days for drivability and some quick glances at A/F.

The rich "dip" for lack of a better word is very fast and only comes into play when I try to get the car rolling into first. It is for a split second, at low RPM (and I assume high vacuum) and it is just enough to make a stumble. It is exactly as the common lean complaint except my O2 gauge drops to 10 instead of shooting up to 16.
