odd request from mechanic

i went to a place to get 42.5 pilotjets, he gave me a 40 and told me its possible to fit it if you loosen the "mixscrew" (idk how to translate it) by 0.5

can someone fact check? guy sounded like he knew what he was on about and i'm a noob but it still sounds so weird to have a smaller pilot than the original
