The invention relates to a stopping device for a positive ignition engine. The inventive device comprises direct actuation means which act by means of friction on the flywheel (9) of the engine shaft. The aforementioned means comprises a second-class lever which is equipped with: a support point or fulcrum (3) which is disposed at one end on a fixed part of the engine or chassis, a power arm (1) which is disposed at the opposite end, and a resistance zone or point (2) which is disposed between the power arm and the support point (3) and which is designed to act by means of contact on the rotary part of the engine shaft (9). The actuation surface of the resistance zone or point has a complementary shape to that of the flywheel, which is used to ensure contact with the rotary part, and the power arm (1) has a zone that is adapted to the form and shape of the user's finger. The invention, which is particularly suitable for engines that are used to make model automobiles, can be used to stop the engine without the use of tools and with a high level of safety for the user.
