In my younger days I kept close tabs on my fuel use. I bought a '67 96 V-4 (w/ Solex 28/32 PDSIT-4 carb) in May of '69, and over several years I averaged 27.5 miles per gallon. I tended to have a heavy foot and drive spiritedly, especially on back roads. My sister had a '68 96 V-4 Deluxe with the same carb and got better mileage because she didn't drive it as hard. On long trips in her car we averaged 35-38 mpg. In late '71 I swapped in a 3/4 cam, heavy valve springs, light lifters, chrome-moly rod bolts and two-barrel manifold with 28/36 DCD Weber (all available at that time through SAAB's Competition Department). My fuel economy went to 30 mpg. I had a lot more power under my foot, but didn't have to put my foot all the way to the floor to get adequate power. (The car could do 70 mph in third and still had something left.) As long as you stay on the primary and don't push the gas down far enough for the secondary to start opening, the economy on a progressive two-barrel is quite good, usually better than the stock carb. A non-progressive two barrel will drink gas by comparison.
By the time I started driving a '70 V-4 with the FoMoCo carb, I wasn't keeping mileage records.
I don't know how the 34 ICH compares to the stock Solex.
