Carburetor Boiling Issue

I am having an issue on my 1975 Dodge Dart Sport with the carburetor, it’s a 4 barrel and I went for a drive and when i went to leave from my location, the car would start and i looked in the carb and there was a constant leak from one of the boosters in the primary side. And pressing the throttle there was only air coming from the nozzles. What’s going on??
A few things that I have done to help with the hot restarts and E10:

I also added the return line to mine but with an electric fuel pump too. I added a priming button to fill the bowls before each start.
I added a mini starter (Powermaster XS Torque series) to help get the motor turned over quicker on hot restarts.
I also have a phenolic spacer, and I just added a different intake with an air gap between the carb and the block.
