OK... I get this, so those little wheel screws are idle mixture right? I thought you wanted the linkage to open both throttles at exactly the same time... but once running you need to noodle with them again? I guess a dynamic adjustment like this makes more sense than a static one. Ill keep this handy when I get the engine back in.
