Re: F 41 emulsion tube?
F41 is leaner then F16 (look at those big holes).
Measure airhole on 55F11 an 55F21; the one with the bigger airhole is leaner in higher rpm.

Re: F 41 emulsion tube?
i have done many runs on the dyno with my 205 1.3 rallye original on twin DCOEs.
Found out that the emulsion tubes do not really give a load more of fuel on the total RPM range.
But it gives a more consistent mixture of air and fuel, so the in the lambda graphic (on proper dyno with pc) the line has got less vertical movements.

Re: F 41 emulsion tube?
This is a guess but they may be from a weber dcom carb..?
Webers attempt to copy the years of extensive research done by dellorto in their emission spec carbs, basically a lot more and bigger air holes that atomise the fuel to a bigger degree giving it a better burn quality... Known as swiss cheese tubes.
