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.

                                                                    jxs 5/16/07
