As in richer fuel or air?
Euros discribe their mix backwards from US.
Richer in US is air and IMHO Euro richer is fuel.
Any takers?

Richer=more fuel.
Think of it this way. The further the flapper door in the air flow meter moves, the more fuel it tells the computer to inject. The adjuster is a screw that blocks off an air passage around the flapper door. Therefore, if you unscrew the adjuster, you are letting air bypass the flapper door. So it swings closed slightly, leaning the mixture. Screwing in the adjuster shuts the bypass forcing more air to go past the flapper door, opening it more. And enriching the mixture.
