A misnomer for sure. However, I don't quite understand when you said the enricher does not work unless the throttle is closed. ------------- the carburetor is two carburetors in one an inch and a half throat carburetor add or about 15 to 1 mixture ratio for main power. and about a quarter inch carburetor at 20 to 25 to 1 mixture ratio for helping to start. With the main carburetor closed and you open the enrichenor it will empty the plus or minus one tablespoon of gas from the enrichinger bowl very quickly to give you the equivalent of an accelerator pump. If you leave the enrichenor open during an idol it will be so rich it'll start to run rough if you leave it open during flight it'll be a little bit richer instead of running 15 to 1 mixture it may be 16 or 17 to one mixture and that'll still depend on the throttle setting. Once the enriching or float bowl has been emptied then the only fuel that can get into the enriching or carburetor has to go through a little jet in the bottom of the float bowl and that limits it.

I'd expect there to be a limit to how much extra fuel the enricher can supply, so with an open throttle and little airflow, you're going to get a lot leaner ultimate mix.

The carb dont care and works the exact same if using premix fuel on 2 stroke... If using regular gas and an oil injector on 2 stroke, leaving the enrichener open will cause the fuel mix to be rich and the oil to be lean. The enrichenor is generally used to start a cold engine. When the engine is cold all the fuel does not vaporize as well as it does in a warm engine. So by pulling cranking air flow through a enrichener carb (1/4") the airflow is faster and because it has a richer mix plus the accelerator pump action,,, mixed with the limited vaporization due to the cold helps things start. Once running close the enrichener and run on the main jet, the engine should never run lean on gas unless the main jet / jet needle is plugged or partly so. If you want more info let me know.
