Hey Ralph- Sounds like you need to adjust the idle mixture a bit differently... did you already try this? The technique I typically employ on dual 2-bbl Webers is to disconnect all the linkage, then set up the air flow the same all around, then adjust the mixture cylinder by cylinder. I turn the screw in until the engine starts to misfire (too lean), then turn it out until it hits all the time again, then about another 1/2 turn. If the engine was really far off, I go back after this and check/adjust the air flow on all four again (setting my idle speed in the process) and recheck the mixture again. For the dual 1-bbl variety, a similar method will work. The only difference might be the figure of "1/2 turn extra" after it fires evenly. You could experiment a little bit: do just this, then try 1/4 less on both, then try 1/4 more on both and see what you like best. Remember, it's best to do all of this work with the car in drive (and A/C on if applicable), so you might need a buddy to hold the brake for ya.
