Hi all, I spent yesterday fooling around with my weber idf 40's. by following mrbubbleheads instructions. With my snail, I got all four barrels pulling the same by adjusting the air bleed screws. I then moved on to the mixture screw. The mixture screws have absolutely no effect on how the engine is running. I can back them out or screw them in and there's not change in the idle. Is there something else going on here? In general, after adjusting the bleed screws, the engine is running pretty smooth. Any ideas? Thanks for reading.

sounds like your idle speed is high and off the mixture circuits. Reduce the speed and try the screws again
