Carter manual choke q's

Hi all.
I've got a question about the manual choke conversion on a Carter 1BBL.
There is vacuum being pulled through the choke assembly, so do I need to block the vacuum?
The black cover of the choke spring assembly is broken, so I'm planning on turning a "blank" just to blank off that part of the carburator.

What are your thoughts about this?
If someone can maybe show me a pic of their manual setup it would be much appreciated!

Thanks,
Okkie

 

I'd stick a bit of silcone and let it cure on the hole.
It's more a vacum leak if you don't.
Bettter to do a 100% J.O.B. than leave it sucking air

Sometimes some of my body parts suck wind, so my wife says!

 

Soooo, that's the way the wind blows!

 

Thanks Drednot.
That helps a lot.
