Carburetor understanding

I’m not sure who needs to see this, but this guy 3d printed a small engine carburetor and filmed it running a small rototiller in super high speed frame by frame. Each basic control and operation of a carburetor is explained and illustrated in the video. I do think I have a pretty fair understanding of how a carb works but physical representation is a big thing for a lot of people to learn and understand. Some great information that can be applied all across the spectrum of engines and how they work to run enjoy folks!
