No did not, decided to put it away to solve another day.
It's been in my heated attic for a bit as the last post was 08.
Time flies.
Hi Rugyboogie, I also have an AT 666 that won't hold vacuum. Some time ago Raul suggested a new securement line around the perimeter but I have too many other projects ahead of this one.

If your test identified the air intake valve, can that be disassembled and repaired or replaced with help from a tire or bicycle shop?
Yes, guilty part is little rubber valve-in. I found no solution to replace it. There are special form rubber T insert. It's looks good, but not hold vacuum.
Only solution to close valve with rubber cup. Or DIY valve.
My skill not so high.
