Ughhh I need help. Tuning issues.

If you are running in the 2500 rpm and lower range you are using the idle circuit.
Make sure the float levels are stable and in the middle of the sight glass, set idle mixture to 13.0 engine hot in neutral. Richer idle fuel mixture is a compromise for driving the car on a warm afternoon and going home in the nice cool evening air. I always get the pump shot close for street driving and fine tune it the track using 60' time.
It's not just the temp drop affecting your AFR, the relative humidity also rises after sunset and density altitude drops like a rock after sunset.
IAT, MAP sensors, etc do this in real time with FI. You have to find a compromise point with a carb on the street.
