COMMENTS: 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.

                                                                     OA 5/29/08
