<p>An ignition timing device (10) for timing an engine having a timing port (12) includes a sensor (16) securable in the timing port (12) to provide a timing mark signal (13). An ignition sensor (18) is adapted to provide an ignition signal (19). A comparator (22) receives the timing mark signal (13) and the ignition signal (19). The comparator (22) provides an output signal (23) indicative of substantial simultaneous occurrence of timing mark signal (13) and the ignition signal (19). An indicator (24) receives the output signal (23) and is operable as a function thereof.</p> |
