However, I've also heard that since YS engines have a built-in pump, they don't have this requirement. Is this true?
Correct. The regulator will prevent fuel from entering the carb even if the tank is several feet above the carb. Yes, YS engines are pretty easy to tune if you use your brain. I don't even bother with the other brands anymore (maybe with the exception of the new OS supercharged FS-200).
