Hey! ... I am the Guy who wrote that Writeup and Shoot all those Photos,
and very Respectfully and Kindly, let me Tell you that You're Wrong once again, in two things,
First: I do not Live in oz, I Live in Honduras, Central America (Between Caribbean Sea & Pacific Ocean)
Second: The Weber Carb I Mounted on my Subaru "BumbleBeast", is Not Sideways at all.
Oh yes, I was up 'till 1:00 am reading about your "Bumblebee", have bookmarked it separately for further reading..
I do apologize for putting you in Oz, I was on with my brother there about something, got my wires crossed.
Back in the day, I was involved with racing, knew a lot of Formula Ford people, who lived and breathed the Weber 28/36 DCD, the ancestor of the carbs we are discussing here. I had quite a Weber library for a few years, tossed it all about five years ago..
I do remember that Weber was adamant about the orientation of the carburetor with respect to vehicle travel, which I was trying to point out. That said, never mind the theory if what you have done works, as I reckon yours does. I hope it works out of OCD as well. If I were to try to go that route, I'd be inclined to begin with a 36 IDF.
That said, I'm pleased enough with the SPFI on my Loyale to leave it there. IMHO, Weber carbs are OK for racing, FI has 'em beat for street use. I once had an Alfa 1750 Berlina, and two engines for it, one with the Spica mechanical FI, one with 40 DCOEs, could swap engines before lunch. I live in CA, the Weber engine wouldn't smog.. After a while, I sold the Weber engine, the FI worked better, especially as the weather changed..
