Your circle is on the secondary side.

Have you checked your float levels?
Have you checked the pump lever setting?
I checked the float level some time ago. I found these instructions for doing the pump lever but the instructions describe “First, make sure that the fast idle cam lever is disengaged so that the operating lever opens all the way.” I’m not familiar with what the fast idle lever is.

Any pictures I see of a similar carb on the internet shows another accelerator pump nozzle on the secondary side.
