Yes, all Packards, except for maybe some of the early years have them. There are there to warm up the carb when the engine is cold, especially in cold weather. The problem is if the valve gets stuck, then the heat from a hot engine is then baking the carb. This valve is also the same function as other heatriser systems on other carb equipped cars.
