I was quoting "Lotus" Dellorto set-up's. Lotus numbered their carb set-ups (Stromberg & Dellorto intermingled) sequentially as set-up changed through the years and models. Spec-1 through Spec-10 cover the evolution of the Lotus version of the naturally aspirated 907 and the 912... Elite, Eclat, Excel & Esprit. Lotus only used DHLA 45E's on their N/A 9XX's, never 40's, and their Dellorto set-ups are covered by...
Spec 1, 1974 DOM 2.0 907, 38 mm chokes (too big)
Spec 3, 1975 DOM 2.0 907, 35 mm chokes (too small)
Spec 5, 1976-1980 Euro 907, 36mm chokes (just right)
Spec 9, 1980+ 2.2 912, 37mm chokes (Lo-CR, 9.4:1)
Spec 10, 198?+ 2.2 912 HC 37mm chokes (Hi-CR, 10.9:1)
I run Spec 9 on two almost stock 907's and on a hotrod 2.2 907, and they run beautifully.
