Question about 1965 Ford Mustang
Hello, I have a few ideas to give you. I am thinking the fuel line may have a hole in it somewhere and that you are losing the vacuum draw at low speed. You may also have condensation in the gas tank or gasahol may have separated and you are getting a glub of something other than gas that is rolling around the inside of the gas tank. When you go to stop, the gas moves to the front of the tank, leaving the heavier contaminates at the fuel pump pickup.
That being said, there may also be a problem with the fuel pump pickup itself inside the tank. As a note, for awhile the gas stations used a foam ball filter in their pumps. But when the netting detriorated, the loose foam balls were injected into everyones' gas tanks. (rice size pellets)
Another thing you can do is add a vacuum gauge to your instrument cluster. It is both nostalgia and functional to use a vacuum gauge. Also the proper carburetor setting is made using a vacuum gauge, turning the air mixture to the maximum attainable reading, then backing off so the vacuum level is about 1lb from peak setting favoring more air(more open).
I would be interested in what you found from inspection.
