I've got a 401 with a 2 bbl carter carb. The carb has what I call a flat spot. If you give it a little gas, it's okay, if you give it just a little more, it starts to stall(and frequently does under load), if you give it enough gas to hop over the flat spot, the car moves just fine.....albeit with a bit of a jerk. The carb operates the same whether the car is being driven or operated manualy. The carb appears to be freshly rebuilt, as it is spotless. It is a model 2980S. Here is where it gets interesting. The Invicta is a 1959. According to my research the Engine is a 1962 401 (based on the I in the engine number) The carb, according to "the carburetur shop" belongs to a 1960 364 and is a WGD vs a AFB(What does that mean?). (which explains the 364 etched in the air cleaner). Carb is a Carter 2980S So, does the carb being designed for a 364 instead of the 401 it's attached to have anything to do with my problem? My 65 wildcat wants to run away at idle.....where the 59 Invicta has to be convinced to go.....is this the 2bbl vs the 4bbl or does this have more to do with the different transmission designs? Any help would be appreicated! Thanks!
