Pics would be good, also where are you taking the measurement on the carb?

29mm smoothbores have brass floats. They also have only one fuel inlet located between carbs #2 and #3.

Not all Mikuni sbores have a 17mm bottom plug, some of the early ones have a drain plug, I also have a set with plastic floats. What they do have is a slide that goes around the needle jet block giving a straight venturi and a combined needle jet and emulsion tube and there is only one casting for both left and right side carbs with redundant bosses left undrilled.
