UNSATISFACTORY performance of an aircratt engine often leads to the ignition system being suspect without there being positive proof that this is where the trouble lies. A complete change of sparking plugs may have to be undertaken; alternatively other ignition components may have to be removed for substitution, bench test or examination. All this work may be necessary to locate the fault, and, in the end, it might even prove not to be in the ignition system at all.
