Still stalling after carb rebuild. ???

The bottom of the bown vent rod is activated buy the large flat washer on the curb idle screw. At idle the washer will hold pressure on the end of the rod holding the vent just barely open, when you open the throttle the washer moves away from the rod letting the vent close on the bowl.
Idle circuit in carb is plugged and throttle plates are to far open for vent to operate and motor is not staying running do to plugged idle circuit.
