oldsmobile choke regulatgion???
 

i have a 1966 dynamic 88 with a 455, recently a part that acts as a "middle man" between the gas petal and the carberator snapped. it appears to be some sort of choke regulator but i cannot find it anywhere. please does anyone know what it is or where i can get one.
thanks
