Some notes on slide valve and rotary carburetors.Rotary carbs offer a larger response in the middle of the powerband. This works well for off-road applications when throttleresponse must be varied.
Slide Valve carbs provide greater response at the beginning and endof the power band. This works well for on-road and racingapplications for fast take-offs and high speed.
