    Textbook symptoms of fatal lean-out. That's the easy part; the hard part is figuring out the cause(s). There could be more than one factor. I'd start by checking for a tiny vacuum leak, low fuel level inside the float bowl and cleaning the pilot jet. Next steps would be adjusting the pilot airbleed screw for a richer mixture and setting the curb idle screw to provide a little more throttle opening at idle. These are only intended to be starting points. Carb problems can be really tough to pin-down.
