摘要： A compression release mechanism for an internal combustion engine wherein a rotatable pin positioned axially parallel to the camshaft is rotatably received in the camshaft lobes, and has an auxiliary cam surface mounted at an axial end thereof. The auxiliary cam surface is adapted to extend above the outboard camshaft lobe to engage one of the valve lifters to thereby activate a compression release valve when the rotatable pin is rotated to a first position in response to low engine speed. The pin is rotated to a second position in response to high engine speed whereby the auxiliary cam surface is adapted so as not to engage the valve lifter. The pin is rotated by means of a centrifugally activated flyweight in response to engine speed.

摘要： A single cylinder air-cooled internal combustion engine has a bracket which is mounted to the engine encircling the crankshaft between the flywheel and the crankcase. A plurality of engine accessories are mounted to the bracket as a subassembly prior to assembly of the bracket to the engine. The engine accessories include a safety brake, a throttle control lever, an electric starter, an alternator, a finger guard and a cooling air baffle.
