BBD big bore 2 barrel carb help

Hi I'm new to the sight and actually a B body owner but I came across some threads here that led me to think i could get some help.

I have a all stock 361 with what appears to be a rare BBD big bore 2 barrel carb. I can start my car fine but once is warms up and I kick the idle down it stalls. It seems that the idle fuel circuit is plugged or not feeding fuel to the bores. I have removed the carb to rebuild it but thought I'd ask for some direction and recommendations first.

the only help I have is from an old shop manual.

Here is a thread about the same carb.
