Installing new Edelbrock intake & carb

[Crawdad]

If you don't already have a vacuum gauge, I'd get one to tune the idle circuit of the carburetor. It makes all the difference in the world. I put an offroad kit and a little different metering rods in mine also. I'm sure it will fire right up out of the box though.

Here is where I show my lack of experience in the carb world. What is a vacume guage? Is this another guage that is installed on my dash?? Who makes a good vacume guage?
