Inconsistency

Well, I'll go this route.
.
First I would want weather station input to see if it's changing & then how much. Then see how it follows how the car is running. Next, besides an RPM sensor I would want an output shaft sensor. With these you could see if there was a traction or transmission problem. Next I would want either a pyrometer or O2 sensor. With these you can see where your fuel metering is @ & if it fell over the edge on the bad run.

Without the sensors,

There are many things that can go wrong inside a carb. Do you have a known good piece that you can swap onto the car ?
