A centrifugal clutch mechanism operating with the drive shaft or flywheel of a small motor of a hobby vehicle (boat, car, etc.) or power tool and on the driven shaft of the same types of equipment for the purposes of torque transmission control with adjustability. It includes two centrifugally operated weights, counterpoised against springs, which press against a clutch drum with increasing force as the rotational speed increases. At low speeds the springs maintain the weights out of engagement with the drum. As the speed increases the weights come in contact with the clutch drum to drive the drum. In order to start the engine by hand or otherwise turning the driven shaft a pair of low speed automatically releasing pawls are provided for engagement with an annular ratchet.
