Yo coolgal, I also had idling problems before in my carbed engine and i would just like to share some tips.

1. First of all, carbureted engines are sensitive to changes in weather and altitude. For example, if I had a tune-up at summer and I suddenly went up to Baguio, there's a possibility that the car would not be in tune and you have to do another tune-up at that weather and altitude. Since it is Dec, it's possible that you just need a new tune-up.
2. Dirty carb- using carb cleaner would only reach the externals and the choke and some areas at the mouth of the carb. Passages inside would not be cleaned. To clean this, you have to use a carb cleaner that is mixed with the gas at the tank. This would help cleaning it up further.
3. Vacuum advancer- there are 3 screws that are adjusted at tune-up. The idle up for fuel, the screw for the air and the vacuum advancer. Try adjusting the vacuum advancer with the aircon on and put it at the right RPM. If it doesn't budge, then the vacuum advancer might be busted.
4. Solenoid
Hope this helps, HTH.
