I wouldn't think so, it sounds more like a vacuum leak. Is it still carburated or injected?

Ah then it is most likely that the card needs an overhaul, probably some thing got in the idle ports inside the carb or a gasket went bad, with this garbage they call fuel today is really hard on carbs that have not been updated for the fuel.

Would that cause me to smell gas fumes loud

Flooding, also could be carb related, if the float is sticking then fuel could overflow out of the vent and spill over the carb and into the air cleaner assembly and possibly onto the engine itself causing a fire.

The problem with replacing the carb is a lot of times you wind up with a carb that is in worse shape than the one you had, the only times I have replaced a carb is if it was damaged or the throttle shaft holes were too far gone so they couldn't be redone with bushings, then I had to do work on the replacement to make it perform properly. But the choice is yours, if you are doing the work yourself then replacing the carb might be best for you.

Have the carburetor that's on the car rebuilt. Do not buy a rebuilt carburetor and turn the old one in for the core charge. Believe me, I speak from experience!! HTH. -Jim
