The only thing I've done is add a glass bottle gravity feed oiler. It's a gravity feed oiler that you would see on a lathe for oiling bearings or for oiling ways. I added it to my air tube so that water will drip into the path of the air stream. Which in turn adds oxygen to the burn and supports a cleaner burn. I had to play with the drip ratio to find the sweet spot. I found out by mistake that by adding a lot more water and by getting the burner chamber temperature up to about 1500 degree's. The water will clean the inside of the burner for me. Other than that, I haven't done anything else to it.
Note: Added a picture of a glass bottle gravity feed oiler that I put water in.
