Until you open the carbs,  it's just speculation as to what DBE sent to you.   Des Hammil's book doesn't discuss the Power Valve.   Or at least I didn't see it during a quick scan the other day.   However the Lotus Service Notes (aka Workshop Manual) for the 1983-87 Turbo Esprit covers it in the carb section.   I could sweet-talk a friend with access to Adobe Acrobat to scan it into a PDF,  but don't hold your breath waiting.

Euro-stock OEM J-H Dellorto DHLA40 carbs were equipped with a Power Jet...  size 70.

Lotus Spec-10  2.2 912  and the 1988 Esprit NA (naturally aspirated 912) DHLA45's  used a 70 Power Jet.

Lotus Spec's  1,  3  & 5 did not have a Power Jet.
