ABSTRACT:
A combustion engine according to the present invention has a unitary fan-pulley assembly (F), in which a cooling fan (8) and a starter pulley (9) are formed integrally with each other. The cooling fan (8) is fixed to a crankshaft (1). The pulley (9) receives a starting force when engaged with engagement pawls14bintegral with a recoil starter (14). A bracket (11) is fixedly mounted on the crankshaft (1) together with the unitary fan-pulley assembly (F) for urging engagement grooves (92), each defined between neighboring engagement projections (91) of the starter pulley (9), in an axial direction of the unitary fan-pulley assembly (F).
