I've seen more VM26's with high fuel level that I care to shake a stick after. The floats are typically adjusted with the tang either flat, or slightly down, which lifts the float, and drops fuel level. The problem get serious when the float tang is bent down to the greatest extent possible, and yet the fuel level is still too high. At that point, it's time for new float valves. I typically use Keyster brand. And even with these parts, it's often necessary to adjust the float as high as possible.
Question is, how much does the float itself contribute to the problem?
I've bought aftermarket floats and used those, but they don't inspire confidence, and are often heavier than the used parts they are replacing.
I've found a reference connecting the OEM Float PN 16031-031 to Mikuni VM24/171 floats, which are made from brass. Has anyone ever used these brass floats in their VM26/VM28 carbs? I'm starting to wonder if that would allow the float to be installed with the tang flat, like the carbs were when first built?
