Totally! I was just reading an old magazine article about how tuning by ear and feel on a carbureted engine gives you a better gut sense for how everything works together. It said you start to notice little changes in the engine sound that a computer graph might just smooth over. Isn't that the whole point, to actually understand the machine?
Nodding hard at @wade_perez on this one. That gut feeling you get from messing with a carburetor is something a screen just can't teach you. Sure, a graph shows you the perfect numbers, but your ear learns the story of the engine. I kinda worry that skill is just disappearing, which sucks. We shouldn't lose that raw connection to how things actually work, you know
Watched my buddy spend two days chasing a weird idle with a scan tool. Finally just listened to the engine and had it fixed in twenty minutes. The computer said everything was fine, but his ears knew better.
