Well if its not holding vacuum it's definitely bad, so it's not a bad idea to change it. I also heard that the float can sometimes get holes in them and this leads to the carb running rich. I'm not sure if this only applies to Holleys or not. After you replace the choke pull off valve you can take a vacuum guage and readjust your carb. There should be a couple of tiny screws on front of the carb near the base on each side. A special tool or super tiny screw driver is needed to make the adjustment.
