A two-stroke internal combustion engine comprising a cylinder (10; 50) with a movable piston (11; 52) in it, which cylinder at its one end has a combustion chamber (16: 51) and at its other end is connected to a crankcase (15; 53). The crankcase and the combustion chamber are mutually connected via a scavenging duct (17; 56), whose opening and closing is controlled by the movement of the piston, and a carburetor (20; 55) is via an inlet port (21) connected to the crankcase. In order to simplify starting the engine it is provided with a device (23-26; 61-65; 70-72) for supply of fuel to the scavenging duct (17; 56) adjacent the combustion chamber.
