This YS Engine YSS2035 kit provides RC-scale replacement screws listed for the 56SR carburetor series. The set is designed to support disassembly, cleaning and accurate reassembly of model carburetors.
Installation tips: verify the YSS2035 numbering and visually check that head style and thread length match your 56SR parts before installing. Clean mating surfaces and apply correct torque in small increments to preserve thread integrity. The screws secure needles, linkages and housing parts so they influence setup stability and tuning repeatability.
