COMMENTS: Some notes on rotary and slide valve 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.
