No. 4"A" reproducer rebuild question

[Mitchell_5898]

Almost finished rebuilding my 4"A" pot metal reproducer. Only problem I am currently having is that the new isolator flange gasket I bought is sitting loose and just a little proud of the throat. Now I'm not sure if it sitting a little proud is an issue, but it sitting loose in the throat has me concerned I am going to get air leakage, plus now half the time when I'm adjusting the reproducer to "drop the needle" the reproducer comes off my tone arm. As in, the reproducer comes off and the gasket is still sitting on the tone arm, and the screws are left in their holes. It almost feels like the rubber is too soft and gives too much for the screws to hold it securely in place. Has anyone had this issue before? Ive tightened the set screws more but it seems to have little effect. Any help would be appreciated, I really don't want to spend another 25 bucks on another flange.

The gasket in question, I bought off ebay from Gettysburg Antique Phonograph

I have used black silicone sealant to fill the gap and seal the isolator rubber. Be sure everything is located properly before allowing the sealant to set.
