0Mechanically timed ignition is easy to understand and straightforward to diagnose and repair, which is good because it's one of the most likely things on an older car to die and leave you in the lurch. Rob Siegel, better known as the Hack Mechanic, explains how mechanical ignition works and discusses in detail how to set timing and advance. There is also a full chapter on troubleshooting mechanical ignition problems. Illustrated with over 100 photos and diagrams and supported by clear, step-by-step instructions, the Mechanical Ignition Handbook features sections on ignition basics and components, recommended tools, adjusting point gap and dwell, locating the timing mark, finding top dead center, testing coil resistance, and retrofitting breakerless electronic ignition. Applies to vintage cars from the 1950s to the 1980s that have either points and breakers or mechanical ignition advance.
