I have removed the carburetor of my car for repair . Its a Aisan 14120 carburetor. My car is a 1987
Toyota Tercel 4wd 1452cc 2bl manual driven car.
I know the functions off all the components instead of this shown circled in the following picture.
It is a two barrel carb. That part has a one orifice for the secondary barrel throat. Inside this small chamber, there is a plate like Valve. Other end goes to the intake manifold.
I added some more pictures. It lies in the direction of the arrow in top view.
Can tell me What is this part and what is the function of it?
