You will need a copy of the service manual to set up the carb properly. You can find one linked in the manuals forum. Print out the fuel section for reference. Unless you follow the manual 100% during reassembly you are likely to fail.
The manual lists the carb part number (Keihin) as well.
As for carb kits that actually fit and work..? There are two choices ONLY: Stock OEM parts sold by Honda, or a genuine Shindy Carb repair kit. If you buy a Shindy kit on eBay or Amazon you might be getting ripped off by the lying scoundrels that those corporations "sponsor". Shop carefully... buyer beware!
That said, there is usually nothing wrong with the original parts in Keihin carbs. Clean them up carefully and reuse them where possible. The originals will outlast and outperform (especially OEM jets!) all others, including Shindy!
