Engine Carcurator hose help

[slopoke]

I need help to ensure I temporarily adjust the carburetor hoses for a test. Currently this is how it’s set up normally. And the blue circle is what I need to adjust to… but I’m not sure where they go. Does one end just stay open? If someone can help explain what colors adjust to where I’d appreciate it. My friend that did it is two hours away and I’d prefer not to have to flatbed it to him to get this setup. Thanks for teaching me.
