I was wondering if anyone has used a Mikuni 28mm Flat-slide carb on a highly modified Honda GX200 engine? Specifically, what sized main jet did you use burning Gas? I have one and with the stock main jet it runs lean as hell, way leaner than a carb usually runs out of the box. I've used a lot of Mikuni's, mostly on Harley engines but a few round slide ones on small engines, and as they come from the factory, the jetting is usually close enough that it will run at least decent, but this one runs like S**t! I haven't yet pulled it apart to check the float level etc, and I almost think it has a problem with it other than the jet size. I thought I'd ask you guys what your experiences have been before I tore it apart. The 22mm round slide ones I've used ran good out of the box and took one jet size bigger to run perfect. The 42mm flat slide ones I run on Harley engines usually are spot on with the 160 main that it comes with and usually need 2 or 3 sizes smaller pilot jets to get the slow range running correct. So can anyone help me? Thanks!
