Small Engine Failure Analysis and Repair: Practical Methods for Diagnosing Mechanical Problems, Fuel Delivery, Ignition Systems, Starting Issues, and Power Loss (Engineering the Machine)

Your mower won't start again. Or it starts, runs for two minutes, and dies. Or it runs fine at idle but bogs down the second it hits a patch of thick grass. Sound familiar?

Most small engine problems aren't mysterious — they just look that way if you don't know what you're looking at. A rough idle, a hard start, a sudden loss of power under load: each of these is actually the engine telling you something specific, if you know how to listen.

That's what this book teaches you to do.

Small Engine Failure Analysis and Repair is a practical, no-nonsense guide built around one core idea: diagnosis should be a repeatable process, not a guessing game. Instead of randomly swapping parts and hoping something sticks, you'll learn to think the way an experienced technician thinks — narrowing down the actual cause before you ever pick up a wrench.

Inside, you'll find clear, step-by-step coverage of:

Why engines fail — and how to trace a symptom back to its real root cause Fuel delivery problems, from stale gas and clogged carburetors to modern fuel-injected systems Ignition system diagnostics, including spark testing, timing issues, and weak or no-spark conditions Starting failures, whether it's a dead battery, a bad starter, or a mechanical fault preventing the engine from turning over Compression loss, valve problems, and other internal mechanical issues Power loss under load, rough running, surging, and hesitation — and how to tell them apart Cooling and lubrication failures that quietly wear an engine down over time Preventive maintenance strategies that actually extend engine life, not just checklist items nobody follows Whether you're a homeowner tired of paying a shop for a five-minute fix, a small engine hobbyist who wants to actually understand what's happening under the shroud, or someone starting out in repair work and looking to build real diagnostic instincts, this book was written to meet you where you are and take you further.

Every chapter is grounded in real-world reasoning, complete with practical workflows, comparison charts, and field-style case studies that walk through an actual diagnostic process from first symptom to confirmed fix — not just theory, but how that theory plays out on a real engine with a real customer waiting.

So — are you ready to stop guessing and start diagnosing?
