The first and second members 12 and 14 are secured to a base portion of a distributor assembly or one end of a crankshaft to adjust the timing of an internal combustion engine. The engine timing is easily adjusted to an advanced or retarded position in relation to a zero degree setting by counting from a zero degree orifice 78 and 80 in both the first and second members 12 and 14 in a corresponding advanced or retarded direction, a quantity of orifices corresponding in number to a predetermined degree of engine timing. The selected orifices in the first and second members 12 and 14 are aligned and an index screw 16 is inserted thereby securing the position of the first member 12 in relation to the second member 14. | |
