Going to check my vacuum (with a vacuum guage)

I have a 1968 200ci engine with a stock distributor, with the exception of Pertronix electronic ignition. *FlameThrower coil and Holley 2bbl carburetor*

The carburetor still refuses to cooperate. I have armed myself with a vacuum gauge. The directions tell me to connect the hose and gauge to the intake manifold. Alright, I can handle that, but what do I do with the vacuum hose I disconnected? Do I leave it alone?

Thanks,

Justin :wink:

P.S. The ex's dad got the carburetor tuned enough so that it does not stall and has slightly better acceleration, although, on the test drive he could smell that the carburetor was running rich (I drove past him).
 
I think you probably would want to get some vacuum fitting tees and adapters so that you can keep the engine vacuum lines connected to vacuum and tee into the line with the guage. Many items connected to the vacuum will affect idle quality and idle speed if disconnected. So if you are trying to assess engine vacuum, you need to have everything hooked up. For example, the distributor will normally advance idle speed and increase engine vacuum when the vac advance is connected.
