Like i said, i dont know if its right or not.
Lets go with the fact that carburetors work on vacuum. We are not talking blow through carbs.
So if my blades are open X amount they want to be drawing X amount of air.
Now if im doing 70 at cruse with the blades mostly shut and a high pressure area above my carbs. Is that high pressure area more than the vacuum of the engine?
What happens then?
