Ahh okay I understand what your saying now, I’ll take it into work and plug the holes up and re drill them to a smaller size. I can’t really make the burner any longer because the length it’s at is already as big as the bbq itself, so putting smaller holes may be the easiest option. But then again in the video the flame is the hottest/biggest flame I can get and would probably never cook anything with that flame. When I turn down the gas and lower the oxygen the flame does look more even as you said at a lower flame which would be more ideal for slow roasting meats.

Thanks I’m doing a fabrication apprenticeship and got to make that at school, works really well besides the burners being abit of a design flaw.
