Yes, what do you mean?
The choke is that lever marked "choke". Up is fully closed, down is no choke, in between is partial choke. These carbs do not have the throttle cam to add throttle with the choke so you have to work the throttle to keep the engine running at first
The lever directly works the carb it's on, there are adjustable linkages between the throats to synchronize the plate movements. I try to have them all flat to the airflow at full off, whatever closed angle they end up at is OK they don't all have to completely close but I don't want any restriction at full open.
