It does use both throats, though from any external pics it probably doesn't appear so. I'll look through my pics to see if I have any that show the adaptor 'block' that fits between the carb and compressor if you're interested.
The earliest (and still experimental) versions of the sc setup used really unusual jetting -- main jets that were equivalent to 300s, for example. At the time mine was installed, we were using (this is from memory, so may not be 100% right) something like 175 mains, 175 AC, F16 tubes... I don't remember what the original idles were... I think the chokes were 36 and aux vents 4.5. I also don't remember the acc pump size but I do remember that it has a 0 discharge.
At this point, I'm happy with power but would like to get some improvement in economy. A/F meter tells me it's way too rich most of the time and I believe I can go smaller on the mains... so I've been doing that first, with the plan of experimenting with e-tubes next and idles last.
Maybe I'm going about this in the wrong order?
I can make 'em plenty fun to drive with DCOEs but I'm not highly qualified when it comes to fine tuning the things. Any insights you might have are most welcome.
Best,
