My car has been working great all summer, however yesterday I went to gas up and on my way home it started sputtering and quiting at complete stops.

Checked it out today and it seems that the car will idle then fuel bubbles up out of the carb and it bogs out and quits. Also you used to be able to just flick the key with no/minor pump and away you went, now you need to pump it and hold it down to get it to start. When it does start is sputters and smokes until you get it reved up and let it idle at a high RPM.

Is there a float stuck? or does it sound like a new carb is needed?
