Ok, Let me start.

Wouldn't it make more sense to create groups for these emulsion tubes that are the same size diameter and then concentrate on the positioning of the holes.

For instance, Etubes F8, F7, F2, F3 can be 1 group. (7.5 diameter)
F11, F15 (8 diameter)
F9, F16, F14, F19 in another group (8.2 diameter)

Now lets take alook at the 1 st group.

Although f8, and f7 look the same in the drawing, I am sure they are different. But I am not sure how they are different without conculting the book. However, it seem like the tubes with the holes on top will begin to lean out the mixture as the RPM begin to climb starting from 2500 +.

If you begin to move the holes on the emulsion tube further down, it will delay the mix from happening resulting in a richer mixture during the transition phase at lower RPM.


Now, the reason why I am mention to group the Etube by diameter is so the Etubes will have the potential to flow the same amount of fuel until the holes are exposed, which is caused by the fuel level diplacing from the engine as the rpm increasing.

The way the chart is displayed does not recommend an accurate suggested rich to lean solution.

FYI the small the diameter of the tube the leaner the mixture
