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.
