4 barrel
I have a 4 barrel Rochester on my 350 ci. The trouble I am having is that when it idles it seems to load up and run rich. When you look down the carb you can see gas dripping from the primary nozzles. I have rebuilt it once bathing it in Chemtool for two days. Then cleaning with hot water then blowing dry with compressed air. Runs good part and full throttle but not idle. Have checked for vacuum leaks are none. Put hand over air horn engine runs smoother.

It sounds like the fuel is too high in the bowl on that side of the carburetor. Recheck the needle/seat, the float level setting, and be sure that the float is neither leaking or dragging on the side of the bowl.

I replaced the float with a new one. I even set the float a little low so it wouldn't flood.
When I was putting it together I put a vacuum gauge on the incoming line and vacuum held with the float raised. JIM
