          Some notes on Slide Valve and Rotary Carburetors:
            Rotary Carbs offer a larger response in the middle of the power
            band. This works well for off-road applications when throttle
            response must be varied.
          Slide Valve Carbs provide greater response at the beginning and end
          of the power band. This works well for on-road and racing
          applications for fast take-offs and high speed.

                                                                     tlw 9/5/07
