Great post, thanks for the clarity; just took apart my MARVEL a few days ago and cleaned , etc. due to an unknown leak .All components Ok except mixture screw which was worn, but with some dressing of the tip works fine. The GAV cutaway shows a leather seal below the spring. I purchased the gasket and seals from David @Renners. His GAV seal is rubber, which was missing, and stopped the leak. However the GAV is hard to turn but may loosen up in time. Setting the float parallel to the mating edge was done with a thicker fiber washer that wasn't compressed from age, and it did the job.
