DAE miss the days when we overhauled carburetors instead of chasing ECU gremlins?

I spent last Tuesday troubleshooting a fuel control issue on a 2018 Cessna 172 and after 4 hours of swapping sensors I found out it was just a bad ground. Back in the 90s working on old Pipers you could pop a carb apart in 20 minutes and see the problem clear as day. Anybody else feel like the new glass cockpits take all the fun out of diagnosing hard starts?

Had a 1982 Piper Warrior back in the day where the carb float stuck closed every third cold start. I could have that thing apart and cleaned with a pencil and a can of carb cleaner in under 15 minutes. Now I have to hook up a laptop and pray the diagnostic software actually talks to the plane's computer. Pretty sure my old toolbox had more intuitive troubleshooting than the Garmin G1000 does.

Are you really that scared of a Garmin G1000, Lisa? I mean, I get that old carburetors were simpler, but pulling out a laptop to run diagnostics isn't exactly rocket science. You just plug it in and click a few buttons - way less messy than digging around with a pencil and carb cleaner (though I do respect the old-school approach). Sounds like you're getting worked up over a minor inconvenience that probably takes the same five minutes once you know the routine.
