Vaccum gauge is becoming a forgotten dianostic tool. If you look in the old (before mid-60's) auto manual it is the first tool of choice for figuring out what is going on in a carburated engine. I learned from my Dad how you can use it to check timing, vaccum leaks, and valve and ring sealing. That and a timing light and dwell meter could cover most of the tuning problems. I'll need to check out your Elky link, I'm a Gold member over there but haven't spent much time since I started on the truck.
