Reading an old Otis manual made me rethink my approach to governor rope tension
It said to check for a specific 1/4 inch of play at the midpoint, which is way less than I was taught. Has anyone else found older specs to be stricter than modern practice?

My old foreman swore by a 1968 Westinghouse manual for motor alignment tolerances. He'd say modern guides allow slop that would've gotten you fired back then. The book was falling apart, but he was right more often than not.

My uncle had a 1973 Ford shop manual that called for spark plug gaps tighter than any modern spec. He ran that truck for 300,000 miles without a single tune-up, just following the old book. I tried telling him newer engines needed a wider gap, but he'd just wave the manual at me and say they softened the rules to sell more parts. Honestly, that truck ran smoother than my brand new one does now. Makes you wonder what else we let slide over the years.

That line about "they softened the rules to sell more parts" really sticks with me. Your uncle might have been onto something bigger than just spark plugs. I've noticed the same pattern with all kinds of stuff - from lawnmower carburetors to computer printers, it feels like everything is designed to break or go out of spec faster than it used to. Think about it, 300k miles on a 73 Ford with no tune-ups is basically unheard of today even with all our fancy electronics and tight tolerances. It's like we traded longevity for convenience and nobody stopped to ask if that was actually a good deal.
