The problem many, many times isn't the Webers but the engine.
A four-barrel will run decently with shaky compression, worn valves or valve seats, sloppy timing chain, etc. It's a very forgiving carburetor. Webers are not. They are very much precision instruments and if you have an engine that needs some attention but runs OK with a four-barrel, the Webers will never be happy until the internal issues are addressed. It happened to me and I'm sure many other people.

So true. Usually the last thing that someone who specializes in webers will look at are the carbs. I've only had to have mine adjusted once or twice and usually it's several hours of checking everything but the carbs. When everything is perfect, then it's on to the adjusting the carbs if they need it.
