ABSTRACT:
An engine timing adjustment device is disclosed having a rotating member which rotates integrally with the crankshaft and which has ignition timing indicia on its surface. The device further has a timing pointer wherein the position of this pointer relative to the cylinder body of the engine is fixed such that the position of the ignition timing adjustment indicia on the rotating member with respect to the timing pointer corresponds to the piston displacement for a desired ignition timing. The rotating member may be a flywheel affixed directly to the crankshaft such that it may be assembled to the crankshaft only in a position in which the ignition timing indicia is in the proper desired relationship with the crankshaft throws and, therefore, the piston displacement.
