I finally got done with doing a semi-rebuild on my carbs - I replaced all the choke and secondary membranes which had tears, took off the top portion and removed and cleaned the jets on top and replaced one of the accelerator pump skirts and put new top gaskets on. I did not go all the way down to the float bowl as after that it appeared they were functioning but did blow everything out. choke/high idle seems to function OK. While trying to balance them I kept having issues with the back carb and upon looking found the top nozzle appears to be leaking and continues leaking after shutoff. I took a pic, you can see it appears to leak from the base but a video would show the drip from the nozzle as well. Advice on how to address appreciated. If it helps, I can hear air being drawn in as well when I open the throttle, I thought I had fixed this by fixing a sticking secondary. This carb has been giving me fits in general, after fixing a bunch of other issues hoping this is the last one.

I’m not nearly the pro that some of the guys here are, but I’ve a few dozen carbs under my belt and feel like, if you don’t go 100% with a rebuild…(completely strip down, soak, clean, blow out, completely replace all perishable items and confirm clear passages) you’re just asking for trouble..at least in my limited experience..too many things to go wrong that love to hide from you..
We’ll hear from the big dogs here, soon..

I should have said "accelerator pump nozzle" btw. But I hear you, I started to do that but the gasket between the jet and fuel bowl layer is really stuck on, plus I was hoping to avoid draining coolant and all that, but might have to bite the bullet. I wonder if the replacement accelerator pump skirt is causing this particular issue, I know they are not as thick as the originals. I've had the car 10 years and lord knows when the last time someone went through these.
Looks like a Zenith from the first photo but good for you to confirm anyway
Zeniths. I ended up figuring out how to separate the stuck jet stage from the float stage and took everything apart, inspected it and cleaned it, blew compressed air through everything and cleaned the float bowls although they weren’t bad. Have not had time to restart yet. Possible a couple check balls were sticking. Will post how it goes.
