No ? kinda does sound that simple to me. To change the ratio, I have to increase the quantity of fuel, which I did with the bigger jet. To compensate I ended up closing the mixture screw which reduced the fuel and air. Same amount fuel in both cases. Of course I"m generalizing here, but on a course level that what it seems to be. But you guys are the experts, I'm just trying to learn. thanks again.
You’re right..... it’s not that simple.
The air bleed/ifr relationship determines the A/F ratio mix of the circuit.
The mixture screws adjust the volume of that mix to the discharge ports.
