It will not start, and you have already replaced two parts that were fine.
Most small-engine faults come down to one of four things missing: air, fuel, spark or compression. There is a fixed order for finding out which, and it takes about twenty minutes. Guessing takes an afternoon and usually ends with a new carburettor on a machine that had a disconnected safety switch.
Seven self-contained books in one volume: 174 pages, 8.5 x 11 inches, 70 chapters. Each chapter is two facing pages - the left explains the fault and the mechanism, the right is where you record what YOUR machine did. Covers lawn mowers, generators, chainsaws, pressure washers and snow blowers, two-stroke and four-stroke.
What's inside
- Book 1 - Safety and your engine's numbers — the spec sheet a general guide cannot print for you
- Book 2 - How the engine works — air, fuel, spark and compression, and how to test each
- Book 3 - It will not start — the twenty-minute order, cheapest and most likely first
- Book 4 - It runs badly — surging, stalling, smoke, vibration and overheating decoded
- Book 5 - Fuel and carburettors — the cause of more faults than everything else combined
- Book 6 - Ignition and electrics — the two-minute test that saves you buying a coil
- Book 7 - Service, storage and repair-or-replace — the arithmetic done honestly, including your own hours
A general book cannot know your engine. This one teaches the diagnostic logic that IS general and gives you the pages to record everything that is not.
For people who own machines and would rather fix them than replace them.
