Does anyone have any manuals or diagrams to or for the Mikuni carbs? Washed the crud out of them with carb cleaner,torch tip wire type cleaner and air blower. They are still not functioning. The barrel slides in 1,2 are flutering. 3,4 seem to be fine. Not even running on 2 at all. Rebuild kits are one thing. Knowing where all the microscopic passages are and how they route is trick.
