YS Engine YSS3019 Replacement Carb Body for 120SR  [YSS3019]

YS Engine YSS3019 Carb Body Overview

This RC carburetor body is intended for maintenance and repair of YS Engine 120SR units. The part serves as the central housing for the carburetor assembly and is provided as a spare to re-establish proper fuel and air metering on 120SR engines.

Fitting involves disassembling the carburettor, assessing gaskets and needle components, and reassembling with appropriate fastener torque to avoid air ingress. Inspect throttle linkage, shaft play and the sealing surfaces before completing installation.

During tuning and routine servicing the body functions as the replacement casing for the carburetor internals, enabling worn housings to be exchanged without altering existing jets or needles. Always align mounting points and throttle movement with the engine’s current setup prior to any fuel runs.

This sale covers the carburetor body only; check engine compatibility and follow standard nitro engine safety practices when installing.
