If you close the GAV off, it shouldn't pull a load well at all. If it doesn't change the way it runs then its either stopped up with crud or there is and internal leak running raw fuel into the throat, or both.
Over the last 30 years I have run 4 Model all on original Zeniths . Got 18 to 20 mpg on them all. All the GAV's were set at 1/4 turn open. Never touched them other than to pull them out to choke the car when starting.
