adjusting the fuel/air mixture, not the idle screws on my 94

[hueyhoolihan]

thanks for the answer. and it rings true.

i thought so...i didn't believe that an idle circuit would be designed to also control mixture. idle in carbs of many designs, IME, adjust idle by either cracking open the butterfly just a touch (often adjusted with a screw riding on a boss on the throttle shaft) or a narrow tunnel under the butterfly (often called an "idle circuit") and in the middle of it is a screw that adjusts just how much air can get through it. and i'm assuming on the 94 that there is one tunnel and one adjusting screw for each barrel.
