Could someone please explain to me how the choke linkage is supposed to work.  It looks to me that the link to the activator just slides up and down in a curved slot without opening or closing the choke. Thanks in advance.

the choke just restricts the airflow to give a richer mixture for starting, it will either operate a flap on the carburettor, or maybe on the air filter housing.
