Anyone else out there run a Vacuum Gauge, or know how to use one?
I've always liked having a vacuum gauge, and it can tell you countless things about what is going on with your engine. You can watch in real time the negative pressure changes in the intake system, and try and figure out what it is telling you, and what the carburetor is sensing . You can see things like when your power valve opens, throttle position, engine load etc. I'm going to install one in my 55 on a LS engine. It's more fun to watch than the temp gauge going up and down. https://www.motor.com/magazine-summa...a-vacuum-gauge
