In digging on the web, I came across an article from a professional magazine I wasn't aware of. The publication is 'Engine Builder'. The article was written by Doc Frohmader and had a date on it of June 14, 2012. The title of the article, 'GooD Carbs and BaD Carbs' did not reflect the information presented pertaining to using an existing carburetor on a modified engine, using an existing carburetor application with today's 10% ethanol based fuel, OR installing an aftermarket supplied carburetor on a particular engine.
The article was written for the engine builder or installer, but for those of us that are hobbyists the information may help in avoiding some pitfalls with the carbs you're installing, sorting out, or tuning for adequacy, reliability, drive-ability, or performance. The reality is that EFI systems have a tremendous advantage with their computer feedback technology that monitors exhaust gases and adjusts the engine's air fuel mixture supplied to the combustion chamber for the particular make-up of fuel you happen to have pumped into your gas tank.
In stumbling onto this article I had difficulty getting back to it on the Internet even though I knew the author, the title, and the publication! Too, in finally copying and pasting it for my own reference, I found that I had to do a bunch of 'fixing' of what I ended up with on my Word document. -Words had been compressed in the copying and transfer process.
