Merlin negative G cutout too quick?

Mh. I thought to have read in the Pilot's note of the Spit that mixture should be forward for rich. I try to find this passage.

EDIT: You're right. I must have mixed some stuff up. The pilot notes say richt is backwards and lean is forwards. So actually the lever positions in CoD are wrong.

PS: However I know how mixture ratio works for the early Merlin nonethelss
