    #2 cylinder is below the coil, then it goes clockwise from there. If it runs fine, don't mess with it, someone might have got the distributor in wrong or some other wacko thing happened, so if it doesn't misfire or backfire then I'd leave it alone.

    I have used to the Colortune kit several times and it work excellent. Every time I have used it to adjust the proper air fuel mixture, my vehicles have passed California emissions with flying colors. The biggest challange I had was tuning a 260Z with dual carbs. Used the carb synchronier to balance then the colortune to get the proper air fuel ratio. Took it the next day to the smog check station, and passed by a large margin. /forums/images/graemlins/thumb.gif

    If you mean like tons of HP, no. All the colotune does is allow you to adjust your fuel air ratio for the most desired mixture. More accurate than by ear, or with a vacuum gauge. With proper timing and fuel air ratio your vehicle will run significantly better.
