"The number stamped on a main jet cooresponds to the flow rate of fuel in cc/sec when poored from a height of 50cm. So a 120 will pass 120cc/sec in this calibration test."
That's a heck of a lot of fuel to flow through such a tiny hole. It must be under more pressure than just a 50cm header tank to do that?
"A 10% increase in venturi pressure will draw 10% more fuel. "
I presume that's increase in pressure difference?
Would this all work in a similar way with CV carbs, as on the J ?
I'm guessing it probably would at full throttle.
Feel free to challenge, I am just in research mode

Correction, it should read per minute.

Indeed.

I cant see why not
Of course all this is only theoretical findings. In practice it might be different.
