Rope start

122:). When the rope's grip is pulled, the rope uncoils, tensions the spring, engages the clutch and turns the crankshaft, spinning it to crank or start the engine before the end of the pull stroke. The running of the engine then disengages the clutch. When the user releases the grip, the spring operated reel retracts the rope, setting it up for the next start operation. This recoiling of the rope (as opposed to the rope detaching) gives the recoil starter its name. (Should the engine fail to start, the stopping of the rope pull also disengages the clutch so the rope can be recoiled). This was created by 33: 151:
feature, found on many modern engines and especially larger 2-strokes, is a valve in the combustion chamber which can be held open while the rope is being pulled, avoiding the need to overcome compression while imparting enough angular momentum for the engine to continue. Once the engine fires on

A reel connected to the crankshaft has a notch in it to put a rope through. The rope is wound around the reel and pulled, starting the engine, but once the end of the pull is reached, it comes free, leaving a loose rope in the person's hand. If the engine fails to start on the first pull, the

A number of features are labelled by manufacturers as "easy start," such as the presence of a primer bulb, an additional elastic/spring element between the starter rope and the crankshaft, a decompression release, or simply an engine which the manufacturer contends is easy to start.
