Query: I wasn't impressed...

I'm afraid the authors, while seeming to desire catering to the novice, merely came across as condescending with their choice of phrasing. The book is not set up very intuitively, nor does it lend itself well to general troubleshooting. The troubleshooting offered is positioned in areas of focus that would be difficult to determine without considerable knowledge up front, as opposed to assisting in isolating a problem step-by-step. Further, instead of helping identify parts, etc., the authors seem to assume that you have a thorough overall knowledge of your particular motor, and offer no path to that information. In its defense, the book does go into great detail about disassembling and cleaning or rebuilding different devices and systems. But again, it doesn't help you determine problems, so who'd know what to disassemble? Sorry kids, but major thumbs down on this one.
