a variable, then established the throttle stops (bypass screws every one of the way in) you should have near plenty of to zero stream. But due to the fact absolutely nothing is perfect, there will be some modest diploma of leakage within the shut throttle plates, and after getting utilised the bypass screws to equilibrium for equal leakage thru Every single throttle, you would possibly measure some pretty lower flow charge on each.
