Recoil start

As recoil or recoil starter rope a mechanical starting device for small internal combustion engines is called low-power and low displacement.

It consists of a traction cable, which is wound on a spool in a free-wheel hub along the crankshaft of the engine. To start the engine, the rope is pulled by means of a handle. The rotating reel spool is then engaged over the hub in the crankshaft and to start the engine. The rope is then automatically retrieved by a spiral spring to the starting position. Rare are (or were ) also pull starter, in which the power is transmitted via a program running on a threaded gear is first spurt by the thread with the ring gear of the flywheel of the engine and then drives the crankshaft.

Find application pullstarter especially in working devices that are carried in the hand, such as chainsaws and brushcutters, or for other internal combustion engines, low power, such as smaller generators (up to about 2.5 kW), lawn mowers and marine outboard engines, pocket bikes or certain Nitro engines. Chance pullstarter were also used for larger motorcycles. Motors that are started with pull starter, usually have a capacity of up to 700 cm ³.

Pullstarter older types often had no return spring. Here the starting rope for each startup operation had to be wound by hand on the new Startnabe.
