Pressure in the float bowl is atmospheric, 1 bar. That is what
produces the 'siphoning' when the pressure in the venturi is reduced
by the air 'speeding up' as it goes over the venturi ramp. It is the
differential in pressure from 'atmospheric' in the bowl to just-slightly-
less-than-atmospheric in the venturi that caused the fuel to flow up
the jet, past the needle and 'squirt' if you will, into the air stream.
This is semantics, only. You know all this. :-)

...when pressures are EQUAL on both sides. Remember, this is
how a manometer works! It measures a pressure differential
by unequal fluid heights.
