Found this snapshot from a manual online.
I have one of each, #306A and #653A. I'm wondering which one my bike was supposed to come with, and if I should try and get a replacement so I have two of the same, or if I can run it with the current set up. It states different settings for the two different carbs, so if I were to run both of them would I use two different settings/jets? Someone here already told me that the carb bodies are the same, which seems right (the bowls are definitely different, I can tell). If the bodies are different, then why would the manual settings be different?
Any help would be appreciated, as I work toward getting this bike running I think getting these carbs tuned will be one of the challenges. I've been looking at this 4into1 rebuild kit that would have all of the jets required to run either set up.
