87GL606

Okay so I’ve got the top of the carb off no easy task compared to a holly. Float seems fine. The bowl was full with what seems like new gas although the floor of the bowl was covered in green sludge. I want to finish taking the carb out I’m assuming I’ll have to remove this screw(picture attached)?

So I just got an 87 GL wagon with the EA82 motor. First time Subaru owner. Anyways I hauled the it home yesterday put in a new battery. I was able to turn it over and quickly decided the gas in it had gone bad. I drained the tank and changed filter today in hopes that my problems would be solved. I can pour gas into the carb and get the car to fire and if I keep pouring gas in can even get it to run. Upon inspecting the carb I notice that there is no fuel flowing from the jets. I pulled the intake line and it pumps at pressure when I crank the engine. I pulled the return and have a steady flow of gas there as well. All vacuum lines are hooked up as they should be from what I can tell. My question is what could cause there to be fuel at intake and return but not flow through the jets? Are there any vacuum lines that I should be sure to check? I’ve owned plenty of carb vehicles but, when I look at the carb on this thing I’m completely lost. My first thought was find the bowl and check the float and needle but, I’ll just be honest I can’t even find the bowl on this thing and I can’t even fathom how to remove the carb at this point. If possible please include pictures or describe where points of interest are because this guy is lost
