120SR Carburetor Body Replacement YSS3019 - YS Engine  [YSS3019]

YS Engine YSS3019 Carburetor Housing

This is an RC-scale carburetor body designed for service and repair of YS Engine 120SR models. The component functions as the main housing for the carburetor assembly and is offered as a spare to restore reliable fuel and air metering on compatible 120SR engines.

Fitting the part requires basic carburetor disassembly, inspection of gaskets and needle components, and careful reassembly with correct torque on fasteners to prevent air leaks. Check linkage, throttle shaft play, and sealing faces before finalising fitment.

In tuning and maintenance workflows this body acts as the replacement housing for the carburetor internals, allowing worn casings to be swapped without changing jets or needles. Verify alignment of mounting points and throttle linkage travel against the engine’s existing setup before 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.
