Yeah!
As to the other comments, the Walbro is indeed an all position carb. However others have noticed as well that if the carb is mounted on the aircraft/engine so that the metering diaphragm is in a horizontal position, high "G" loads can cause a momentary change in mixture. The Walbro is an "all position" carb, but not necessarily an "all "G" loading" carb.
The only thing that will give you a perfect mixture in any and every possible condition is fuel injection. (Maybe.)
