ABSTRACT:
To avoid stalling of a two-stroke internal combustion engine as its orientation is changed upon a change of direction in which a working machine such as a chain saw is held, non-atomized fuel is prevented from flowing precipitously into the combustion chamber of the engine. The engine comprises a crank case forming a crank chamber which has an intake port opening into the crank chamber, and a flow control feature at the circumferential inner surface of the crank chamber in the vicinity of the intake port for retarding flow of non-atomized fuel.
