ok, idle circut/idle jet, first 1/4 and take off.

needle, control of flow thru midrange, step down to lean, step up to fat.

main jet, change for WOT(why am i fine thru everything, including WOT up hills or in low rpms, but then FAAAT keeping my speed down)

so then they also sell many diffusers with different diameters, which part of the range do those control/effect? all of it? how? a smaller one is less fuel/more air mix???

or what....

anyone.. diffuser does who what?
