The Bernoulli effect is everything! Without the Bernoulli effect a carb engine wouldn’t be able to consume it’s needed fuel. It’s the Bernoulli effect that makes it possible for the engine to “pull new fuel in”. Without each other they are nothing. The engine doesn’t “pull” fuel up thrue the float bowl, it “pulls” fresh air in thrue the carb, when this happens it cause a Bernoulli effect across the top of the atomizers, that effect then cause fuel to be “pulled thrue” the atomizer from the float bowl. The smaller the opening (smaller carb) cause the Bernoulli effect to be “stronger”. Try blowing across a top of a straw in some water with your mouth wide open vs just barly (like your whistling).
I know I probably used the worst choice of words. Sorry I’m surprised dirt Dillion didnt show up to call my dumb ass out
I love you ma sometimes! Your like a puppy that i haven’t decided To liked yet (edited)
