I’ve never had success working on carbs but I may need to take a stab at these. Watched a video the other day of how it’s done and as usual….looked easy.

If it was the D Ray Smith video, I would strongly suggest you find a different one. There are some things in his videos that could cost you a lot of money. Also, the only way to do it correctly is to seperate the bodies. I'm sure there are many videos with good information. The Honda factory manual is a good resource.
