Lots of great advise listed here on this tricky subject. I thought the Unisyn would solve my dual carb probs too, but as mentioned above, your linkage must be in perfect condition, work smoothly. And your throttle plates MUST open exactly together, not one leading the other. I screwed with the Unisyn for some time without much success, until a friend came by and had the thing working perfectly in about 5 minutes without the Unisyn.
