A specialty nut and specialty ratchet driver device used to start an internal combustion engine, each with an integrated one direction clutch, designed to be an attachment for a commercially available battery operated drill/driver gun. The specialty ratchet driver with an integrated one direction clutch is inserted into the driver receptacle of the socket placed over the nut on the crank shaft of the engine. One end of a drive shaft is inserted into the one direction clutch portion of the specialty ratchet driver device and the other end of the drive shaft is inserted into the chuck of a battery operated drill/driver gun. The torque of the drill/driver gun turns the crank shaft of the engine with sufficient force to initiate starting of the engine. The one direction clutch then allows the engine to turn faster than the drill/driver so as not to impede the engine start up.

A small combustion engine mechanism including an engine, a driven device powered by the engine. The engine having a ratcheting reel mechanism, a recoil starter housing, a shaft member coupled to the reel mechanism, and a bearing member coupled to the recoil starter housing. The shaft member being supported by the bearing member. The engine also has a tool engaging member coupled to the shaft member, the tool engaging member being accessible to a tool driver.

A model airplane engine starting stick is provided with a blade edge engaging roller having a roller surface of a material which will grip the blade edge of the propeller when against the blade edge of the propeller to cause the roller to roll along the blade edge without sliding over and damaging the blade edge as the starting stick is moved with respect to the blade edge to rotate the propeller. The starting stick of the invention includes a handle by which the starting stick can be held and manipulated by a user and a roller attached to the handle to freely rotate or roll with respect to the handle.

Disclosed is an electric starter with a manual turning function. A main shaft, a drive gear mechanism, a shift fork, an electromagnetic relay guide rod and a first return spring are arranged in a housing of the electric starter. A gear shifting mechanism comprises a force receiving component which extends out of the housing of the electric starter and serves as an external force applying point so as to promote the electromagnetic relay guide rod to move rightwards, a normally closed switch for cutting off a power supply of the electric starter when the force receiving component moves to an extreme position, a positioning component for locking the force receiving component when the force receiving component moves to the extreme position, and a first return component which enables the force receiving component to automatically returns to an original state when the force receiving component is unlocked. The main shaft is indirectly driven to rotate by the turning mechanism via a transmission mechanism or directly driven to rotate by the turning mechanism via a turning tool. An improvement is made to a structure of a traditional electric starter without affecting existing functions thereof, i.e., a function of manual turning is added. Therefore, a flywheel gear of a motor can be precisely positioned during maintenance so as to improve efficiency and eliminate potential safety hazards.

A specialty nut and specialty ratchet driver device used to start an internal combustion engine, each with an integrated one direction clutch, designed to be an attachment for a commercially available battery operated drill/driver gun. The specialty ratchet driver with an integrated one direction clutch is inserted into the driver receptacle of the socket placed over the nut on the crank shaft of the engine. One end of a drive shaft is inserted into the one direction clutch portion of the specialty ratchet driver device and the other end of the drive shaft is inserted into the chuck of a battery operated drill/driver gun. The torque of the drill/driver gun turns the crank shaft of the engine with sufficient force to initiate starting of the engine. The one direction clutch then allows the engine to turn faster than the drill/driver so as not to impede the engine start up.
