Abstract: An engine timing plate for cooperating with an engine driven timing wheel and an inductive sensor is provided. An arcuate plate is formed to fit internally within an ignition system housing. The plate includes at least two separate slots positioned on an arc such that the plate is movable, relative to two mounting screws of the housing, over a selected angular range for adjusting engine timing. A sensor mount is included for engaging the inductive sensor in a position adjacent to the timing wheel. An elongate window in the plate is positioned for exposing a timing line that is visible on a mounting surface of the housing. The window provides visual guidance with respect to the timing line in positioning the inductive sensor. The elongate window may provide a series of reference lines for more accurately aligning the plate through relative positioning of the timing line with the series of reference lines.
