The VM26 Mikuni does work on these engines, and works very well. You are the first guy I've ever heard of using a VM28 on one of these engines. So I'm all ears. As far as the flat side goes, What puts me off the OXO is that there is only one slide available. So, if it is too rich up to 1/4 throttle, you have to get a bigger carburetor, and if it is too lean you have to get a smaller one. That makes for very expensive carb tuning. Or maybe, I'm just too cheap.
