right all fours all flat-plane cranks. The weber book says it has to do with the number of cylinders not specifically the firing order. On a four-stroke engine 2 cylinders per carb means the carb is only being used 1/2 the time. Which is why twin webers don't make more substantially HP than a single on a four cylinder. The single uses a plenum to allow all four cylinders to draw effectively using the single carb constantly. On the other hand twin webers can use tuned ports to gain the advantage. But few twin-weber manifold are long enough for that
The other question is about smoothing out the vacuum, which is irrelevant at full throttle
