摘要： A carburetor fuel adjusting device that facilitates control of the quantity of fuel that flows from the fuel chamber to an air intake port of a carburetor by making it possible for the user to adjust an adjustment valve within the limits defined by emission control regulations. The carburetor fuel adjusting device has a cap having two appendages to limit its turning in the lean mixture direction and in the rich mixture direction, and an engagement area to engage a valve extension of the fuel adjustment valves of a carburetor. The valve extensions are inserted through insertion holes of a retainer attached to the carburetor body. When the cap is retained by the retainer in a disengaged position, wherein the engagement area is not attached to the valve extensions of the fuel adjustment valves, the adjustment valves can be adjusted separately from the cap. The cap, however, can be moved forward to an engaged position wherein the engagement area of the cap becomes attached to the valve extensions. In the engaged position, the adjustment valves can be turned in unison with the cap within a range formed by the angle between the appendages which, when rotated, abut against stoppers.
摘要翻译： 一种化油器燃料调节装置，其使得用户可以在由排放控制规定限定的范围内调节调节阀，从而有助于控制从燃料室流向化油器的进气口的燃料量。 化油器燃料调节装置具有盖，其具有两个附件，以限制其在稀混合方向和富混合方向上的转动;以及接合区域，用于接合化油器的燃料调节阀的阀延伸。 阀门延伸部分通过连接在化油器主体上的保持架的插入孔插入。 当盖被保持器保持在脱离位置时，其中接合区域没有附接到燃料调节阀的阀延伸部，所以调节阀可以与盖分开调节。 然而，盖可以向前移动到接合位置，其中盖的接合区域附接到阀延伸部。 在接合位置，调节阀可以在由旋转时抵靠止动件的附件之间的角度形成的范围内与盖一起转动。

摘要： In a first aspect, a carburetor fuel adjusting device that facilitates control of the quantity of fuel that flows from the fuel chamber to an air intake port of a carburetor by making it possible for the user to adjust an adjustment valve within the limits defined by emission control regulations. The carburetor fuel adjusting device has a cap having two appendages, and an engagement area to engage a valve extension of the fuel adjustment valves of a carburetor. The cap is retained by the retainer in either a disengaged position, or an engaged position wherein the engagement area of the cap becomes attached to the valve extensions. In the engaged position, the adjustment valves can be turned in unison with the cap within a range formed by the angle between the appendages which, when rotated, abut against stoppers. In a second aspect, a retaining plate of elastic material having two retainer holes adapted to receive and retain the pair of adjustment valves in a prescribed adjustment position is laid against an outer surface of the carburetor body. The adjustment valves each have a base-end portion and a small diameter portion, the threads of the base-end portion having an external diameter larger than that of the threads of the small diameter portion. The external diameter of the threads of the base-end portion is also larger than the diameter of each of the retainer holes of the retaining plate such that when the adjustment valve is screwed into the screw hole of the carburetor, the base-end portion cuts threads in the retainer holes of the retaining plate to thereby prevent rotation of the adjustment valve.
