A model engine starter assembly is provided which is capable of quickly relieving the engagement between the actuator and the coupling pin upon the start of the model engine and includes a starter shaft which carries a starter pin and defines a shaft axis, and a hub provided with a guide groove which is slanted at a predetermined angle with respect to the shaft axis. The hub has a bore in which a rearward end portion of the starter shaft is inserted for rotational movement relative to the hub. The starter pin is received within the slanted groove so as to move the starter shaft in the direction of the shaft axis in response to rotation of the shaft axis relative to the hub to thereby move an actuator attached to a forward end of the starter shaft into and out of engagement with a connecting pin of the model engine's crank shaft. The slanted groove is defined by a front guide face which terminates at an open end of the guide groove, a rear guide face opposed to the front guide face, and a transition face which extends between the rear guide face and the open end of the guide groove.
