Abstract
The invention pertains to electric starters for internal combustion engines, and in particular, to electric starters for small engines such as used with yard equipment, for instance, lawn tractors, snow blowers lawnmowers, and the like wherein the starter includes a pinion gear having cushioning means associated therewith which is of a variable characteristic such that soft cushioning is initially produced to protect the initial engagement of the pinion gear with the engine flywheel teeth, and stiffer cushioning occurs during high torque transmission during engine cranking. Preferably, the resiliency of cushioning achieved is proportional to the radius of contact between the cushioning means and the starter pinion gear.
