You can make meatballs smaller than the diameter of the throat and drop one in then plunge it to feed, again you aren’t pushing much air in like you would plunging a throat full. I see it on the outlet where if I’m plunging a lot the air pushes right out the exit. So I started experimenting with different ways to feed the juicer that produces less air on exit. Also make sure the teeth on the cone are good and sharp. When I bought mine the teeth were dull and slightly rolled over on the point, guessing they ran heavy pitted fruit through. I sharpened every row of teeth with a small diamond file, very time consuming, and the machine worked much better but then the teeth were a bit shorter and the emulsion was about like triple grinding through the 1/8” plate, so I just bought a new cone, that was a much better solution
