ABSTRACT:
The present invention relates to a device (1) for providing a reference indication of crankshaft positioning for setting and maintaining ignition timing of spark ignition in, for example, automotive piston engines. The device includes a mounting portion (2) and a carrying portion (7). The mounting portion is adapted for rigid attachment to the crankshaft (S) for rotation therewith, and, in use, extends radially of a rotational axis of the engine crankshaft. The carrying portion is for carrying indicia means (9) by which the positioning of the crankshaft can be determined. Importantly, the device of the invention is adapted to assume the task of indicating spark ignition timing from an harmonic balancer (8).
