It keeps the carb from "slamming" closed and stalling the engine when going from WOT to idle quickly.
Actually, this assessment is half right. The actual purpose is to limit emissions, by allowing the throttle to close slowly, limiting HC (hydrocarbon) emissions. On overrun, the additional fuel delivered by the closed throttle unnecessarily enriched the mixture. The slow closing throttle allowed most of the overrun to be limited by the partially open throttle, leaning the mixture under these conditions. Ifyou think about these carbs, almost all of the "enhancements" were the result of the coming emissions era. Though this change was not necessary until the '70's, the experimentation started long before that. Ray
Is a dash pot neccesary? What is the benefit of having it. Will it save on gas milage or screw something up if it's not hooked up. Mine is not touching the throttle. Thanks Keith
