you’re on a lever so may be a bit different, but it sounds wrong, for instance on a high flow basket im 6.5 frank beans 18g in 60/70g out in 25s ish 4 would near choke
take the top off, loosen the red screw and move the black ring one marker, so that the 4 is now 5, in essence, making the old 4 a new 3
then try.
no need to clean with this adjustment.
