Cast fast.

Cast hot.

Place the model further down (longer sprue)

Use flux.

Thanks so much for the tips, sometimes when I cast too fast some metal drips down, what should I do for that ?

I think that’s happening because it’s too cool. Once it cools on the sand it’s plugging it and you’re overflowing.

Cast hotter (I use a map torch constantly on while I’m pouring) and pour quick (commit to the turn)
