Anyone have any experience with Mukuni carbs? I'm a total novice and documentation seems to be hard to find.
I think they're good carbs. Very adjustable. I guess there are "real" mikunis and copy mikunis. The real ones have a larger float bowl and slightly different body shape. Seems like most people use the copies, they seem to be fine. The jets are different for the copies.
I found that you do need to experiment with the main jet size and pilot jet size to get smooth performance through the entire rpm range. Once you get the right jets, you're golden. I run a vm22 on a 5hp briggs and Honda 190cc. With your engine maybe larger, like a 24mm would work well.
Affordable Gokarts's website has a mikuni tuning tutorial, very helpful.
