well i dont have much time but there is a screw that will adjust where the throttle will sit at idle ie. when no acceleration or speed is initiated. If you scew in the screw more, the throttle will not be able to rest full shut (throttle will be more open at idle). If you unscrew it, it allows the throttle torest farther back (throttle more closed at idle) etc. I might be wrong in thinking this but thats what i did.

Other than the minor idle mixture adjustment on S4's (the variable resistor), there is no way to adjust mixtures without adding aftermarket gear. Stock mixture control would allow anyone to make potentially damaging (not to mention illegal) alterations to the engine's tune, and no manufacturer is going to give you that.
