The nice thing about the Rocket 3 carbs is that you don't have to sync all three up "essentially" they are uniquely controlled by a single throttle cable that connects to all three carbs. When I dismantled it you'll notice that the carb on the far left is a slightly different model. I will go ahead and correct that ... the flanges on the other two carbs are there for a reason... the manifold is "hose mounted" meaning that the only thing connecting the carbs to the engine are three rubber hoses. I attached an assembly diagram in case anyone finds that helpful. Also you'll notice its not clear how to assemble the top of the carbs in the diagram so I will also walk through those step by step. Attached is the "manifold", the cleaned carbs, and the assembly diagram.
