The vacuum situation, or lack of it caused by the pods is creating havoc in your vacuum controlled CV carbs. That is why they are not operating correctly at a constant throttle. When you are accelerating, and decelerating the carbs are getting a big change in vacuum so they have no choice but to work, however when at a constant throttle they cannot balance because the pods are not creating enough vacuum for them to even out. A lot of people think you can get CV carbs to work with jet changes, and they might get them to run decent, but they are not running correctly as they were designed to do. To really make them run correctly with pods, you must make changes to the slides.
