Abstract: An arrangement for rapidly halting an internal combustion engine powered implement upon release of a deadman control by the implement operator where a spring actuated braking member engages an annular friction surface on the engine flywheel and the engine ignition system is also disabled is disclosed employing a spring biased toggle moveable between folded and extended positions as the deadman lever moves respectively between actuated and released positions so as to provide a relatively constant force opposing operator actuation of the deadman lever. An additional operator actuated control lever may move the toggle beyond the extent possible due to deadman lever operation for engaging a starter mechanism when the deadman lever is actuated by the operator.

Abstract: A composite flywheel assembly for an air-cooled internal combustion engine including a cast iron flywheel which provides the inertial drive for the engine and a separate blower member having a circumferential array of vanes for propelling a flow of cooling air past cooling fins of the engine. The blower member is a one-piece molded impeller of flexible plastic material and is releasably retained on the inertia wheel by a snap-on interlocking engagement about the outer periphery of the flywheel. The closed end of a starter cup is received over an engine crankshaft and engages a conical skirt extending inwardly from the impeller base to spring bias the impeller against the flywheel.
