Can anyone tell me if I'm testing the "choke vacuum diaphragm" correctly???
I pumped it and plugged the hole with my finger and it won't hold vacuum...
Is us supposed to hold vacuum??

Edit: whether I compress it and plug the hole or pump it with a hand pump it's the same result, it won't hold vacuum... Is that the way this little apparatus is supposed to behave or do I need a new one?
