Overheard a teenager at the parts counter call a 4-barrel carburetor a dinosaur engine part

It hit me that kids today see carburetors the way I saw vacuum tube radios when I was their age. Made me feel old, but also reminded me that the skills I learned tuning a Holley on a 1972 Dodge Dart still work on any engine that breathes through a venturi. Anyone else feel like manual tuning knowledge is becoming a lost art?

Oh man, you're not wrong about the feeling old part, but I gotta gently push back on that "dinosaur" label. A four barrel carburetor isn't really a dinosaur part, it's more like a classic tool that still does a great job for a lot of builds. A vacuum tube radio is completely obsolete for normal use, but a carburetor still works just fine on a hot rod or a farm truck. I think the real lost art is knowing how to read a spark plug or adjust the idle mixture screws without a wideband sensor. Most kids nowadays just plug in a laptop and let the computer fix it, which is fine for a new car, but it takes all the feel out of the tune. You can't cheat your way around a bad idle or a flat spot with software, you just gotta get your hands dirty and listen to the engine.

Buddy of mine @felix_jones just had his nephew over trying to tune his old Chevelle. Kid spent twenty minutes messing with a laptop trying to get it right. My buddy popped the hood, turned the idle mixture screw a quarter turn by ear, and it purred like a kitten.
