Sharing a graph the I ran across a few years ago depicting the AFR response to the main circuit jet, main air bleed, emulsion hole and kill bleed changes. The + and - represent an increase or decrease in orifices size. It helped me understand the nonliner affect the air bleeds and emulsion holes have on the AFR. This also represents how a larger air bleed = richer AFR when the main circuit starts up due to the emulsion effect.
