YS Engine YSS3019 Carburetor Body 120SR replacement part  [YSS3019]

YS Engine YSS3019 carburetor body

This is an RC-scale carburetor body intended for YS Engine 120SR model service and repair. The component serves as the central housing for the carburetor assembly and is provided as a spare part to restore proper fuel and air metering on compatible 120SR engines.

Installation requires basic disassembly of the carburetor assembly, inspection of gaskets and needle components, and reassembly with correct torque on fasteners to avoid air leaks. Check existing linkage, throttle shaft play, and sealing surfaces before finalizing fitment.

In tuning and maintenance workflows this body functions as a replacement chassis for the carburetor internals, allowing you to replace worn housings without changing jets or needles. Verify fit by aligning mounting points and throttle linkage travel against the engine's existing setup prior to fuel testing.

This listing covers the carburetor body component only; confirm compatibility with your engine model before purchase and follow standard RC nitro engine safety and handling procedures during installation.
