The internal combustion engine ignition timing tool (10) installs removably atop the distributor housing (D) after removal of the distributor cap (C), and enables the mechanic to set timing accurately without need of additional equipment. In one embodiment, the tool has a single collar (12), while the other embodiment has an inner collar adjustably rotating within an outer collar. Each has a rotor tip clearance notch (22). The engine is turned to align the conventional external timing marks, and the distributor (D) is turned opposite the normal rotational direction of the engine to push the leading face (24) of the clearance notch (22) against the rotor tip, thus removing all gear lash and slack from the system. |
