Air jet: This is the top of the stack, and the part that has a slot for a screwdriver. The hole that goes through it allows air into the jet to pre-mix with the fuel in the atomizer. These are available in 120, 160, and 185 sizes. The larger the number, the more air will flow through.
Jetting is something that takes trial and error. See our wiki page of jetting instructions for more info.
