This is a problem that in most modern cars is now solved with an idle air control module which regulates how the fuel and air is mixed at idle or when coming down to an idle from higher RPM’s. In the case of older models such as yours, this is controlled by adjusting the idle mixture with a screw on the side of the carburetor. When you rebuilt the carburetor, this may have not been adjusted at that time. I would start by adjusting the carburetor to an appropriate idle mixture which should fix your issue. If you need help having this done, a qualified professional from YourMechanic can come to your location to diagnose the stalling problem and assist with adjustments.
