    Abstract: An automatic decompression mechanism for selectively actuating a cylinder valve of an engine so as to reduce the starting force required to start the engine. The mechanism includes a cam gear, a centrifugal member, and a cover member comprising an integrally formed biasing means for biasing and retaining the centrifugal member in the cam gear. The biasing means urges the centrifugal member into a decompression position when the cam gear is rotating at a lower speed, wherein a projecting portion of the centrifugal member actuates the valve mechanism to reduce the starting force required to start the engine. During normal engine operation, the centrifugal member pivots into a non-decompression position wherein the projecting portion of the centrifugal member recedes below the cam profile surface so as to prevent the projecting portion from actuating the valve mechanism.

    Abstract translation: 一种自动减压机构，用于选择性地致动发动机的气缸阀，以便降低启动发动机所需的启动力。 该机构包括凸轮齿轮，离心构件和盖构件，其包括用于将离心构件偏压并保持在凸轮齿轮中的一体形成的偏置装置。 当凸轮齿轮以较低的速度旋转时，偏压装置促使离心件进入减压位置，其中离心件的突出部分致动阀机构以减小启动发动机所需的启动力。 在正常的发动机操作期间，离心构件枢转到非减压位置，其中离心构件的突出部分在凸轮轮廓表面的下方后退，以防止突出部分致动阀机构。

    Abstract: A spark plug (Figure 1) includes an insulative body (40), a main electrode (20), a ground (26); and at least one intermediate electrode (22A, 22B, 24A, 24B) in series with the main electrode, each having first and second ends and a mid portion in between the ends, wherein the intermediate electrode is partially embedded within the insulative body, such that the first and second ends of the electrode extend from the combustion chamber facing surface of the insulative body and the mid portions embedded in the insulative body such that a gap is formed between the main electrode and the first end of the first of the at least one intermediate electrodes and a final gap is formed between a second end of the final one of the at least one intermediate electrodes and the ground electrode. Fletcher discloses the electrodes placed in a ring-like manner around the outer edge of the insulative body.

    Abstract: A starter mechanism for an internal combustion engine having a spring (88, 84) that is wound during the starting operation of the internal combustion engine. As the operator pulls the starter rope of the engine the starter spring (88) begins to wind creating a force within the spring. Once the spring (88) force overcomes the compression force of the piston the spring will unwind thereby turning the crankshaft of the engine and consequently starting the engine. The starter rope is returned to the housing of the starter mechanism by the use of a rope return spring (84).

    Abstract: A Zero Turn Radius vehicle is provided that utilizes a steering system including front steerable wheels (6, 6a) that is synchronized with a drive system that has dual independent rear drive units (24, 25) to drive the rear wheels (7, 7a) as well as steer the vehicle. The synchronization of the steering system with the drive system allows for true zero radius turning and reduced drag and wear on the vehicle especially the ground engaging wheels (6, 6a, 7, 7a).
