If you want to cheat on the orifice drilling - consider using a mig welder tip - a common Tweco tip comes in a .024 size and I have used that in a waste oil burner as an air jet. I soldered the tip into the ID of a piece of 1/4" copper tubing. Works great - and no small hole drilling. Want less of a hole? Perhaps smacking the tip with a hammer would work to compress the hole in the copper tip.
