Abstract
A mixture adjusting screw in a carburetor for regulating the fuel efflux during engine idling is provided in which the end needle portion of the screw is located in the idle port of the carburetor and a spring is loaded around the rod portion of the screw to hold the screw in position after adjustment so as to maintain its proper adjustment. The screw head is covered by a plug and it is specifically shaped to inhibit easy access of the user to the screw for adjustment purposes. The air and fuel mixture formed in the low-load fuel system in the carburetor is well stirred due to the presence of the spring which is exposed to a fuel passage and is formed into an emulsion flow, allowing stabilized rotation of the engine during idling and high performance thereof in normal running.
