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.)

You are right, but only when the large WB carbs are concerned. WA and WT type carbs on smaller engines do not suffer from this, unless in high G manouvers where the membrane weight makes itself noticeable.
