Carburetor Body for 120SR Engines YSS3019 - YS Engine  [YSS3019]

YS Engine YSS3019 Carb Housing Assembly

This RC carburetor body is supplied for service and repair of YS Engine 120SR models. The component is the central housing for the carburetor and is provided as a spare to restore proper fuel and air metering on compatible 120SR engines.

Fitting the unit requires basic disassembly, checking gaskets and needle components, and reassembly with correct fastener torque to prevent air ingress. Inspect throttle linkage, shaft play and sealing surfaces before completing the installation.

Used in maintenance and tuning workflows, this body provides the replacement casing for the carburetor internals so you can change a worn housing without swapping jets or needles. Confirm mounting hole alignment and throttle travel against the engine prior to fuel testing.

This listing covers only the carburetor body; verify compatibility with your engine model before purchase and follow established RC nitro engine safety and handling practices when fitting.
