AFR misleading? Plugs tell a better story?

Disconnected brake booster hose from manifold, it’s now attached and capped to the rear of carb. Tried a handheld vacuum pump to test brake booster, couldn’t get it to pump up. Not sure if pump is too small. So for now I’ll leave the brake booster capped and disconnected from engine. Thinking it’s bad maybe I’ll go manual master cylinder.
Every time I think I’m going to work on it something comes up. Borrowed a leak tester so hopefully I can do it soon.
Added a valve at inlet to ease up on pressure. Thanks for the info.
