There are vacuum passageways behind the choke housing. Obviously, you don't want them just left open sucking in air. Here is a site with a wealth of pics of them. https://sites.google.com/site/mokmos...ing-adjustment What you're really doing, or should be doing, when you remove an automatic choke is to convert it to a manual choke, but with no manual choke there; you just use the manual choke pieces so there's no leaks. When you look at the pics, you'll see it's pretty straight forward.
