Use an 8mm/1/4" drill bit to get a good center, or a centering bit of that size, even better . Then drill the head for, easy out, extraction. I tap the easy out in then put the easy out in a vise and twist the cab body. Usually the tip can be dislodged by tapping on the carb body. +1 to pushing the tip from the inside, if needed. Anyone that cranks the needles in like that?
