Abstract

Improved pawl assembly for starting mechanisms of small engines mounted on the engine flywheel provided with a bore therein and includes an integrally molded, polymeric pawl, a U-shaped torsion spring and retaining means disposed in the bore of the flywheel. The pawl has a depending shank rotatably fitted into the bore of the flywheel and oppositely extending end portions. The outer end portion, or spur, is adapted to engage a fin or vane of the flywheel to orient the inner end portion, or toe, of the pawl to engage the teeth of the ratchet surface of a pulley type starter. The closed end of the torsion spring is fitted over the shank and urges the pawl to its ratchet engaging position. The spring includes leg portions fitted into the bore of the flywheel and each leg terminates in a laterally extending hook portion adpated to interfit within the retaining means disposed at the end of the bore opposite the end into which the shank is fitted. The retainer includes a slot adapted to receive and hold the hook portions of the spring therein for completing the assembly of the pawl and spring on the flywheel and for tensioning the spring.
