Ok i will do
The only thing is that i need to remove carb for adjusting the secondaries slots.

Also,what i have noticed is the primaries do not show the slots in the same lenght.
I can adjust the left one showing 0.020" making the "square".On that point the other one would be showing 0.035" making a rectangle more than a square.

Passing this point also would affect the vacuum advance, because the only ported nipple that i would have for it, is connected to a hole that is just covered by the butterfly.
