Gosh this is useful stuff. Search engines are dumb in 2026 and you'd have to wade through miles of B.S. to find such pertinent info. Have you seen all these fake sites that contain what appears to be generic a.i. generated content? Many such sites.

Thanks for posting; that second link about carburetors is amazing. Long-form wall of text (albeit spaced and in paragraph form), not for the faint of heart heheheh.
