120SR Engine Carburetor Housing YSS3019 - YS Engine  [YSS3019]

YS Engine YSS3019 Carburetor Housing Unit

This product is an RC carburetor body intended for YS Engine 120SR service and repair. It functions as the housing for the carburetor assembly and is supplied as a replacement part to help restore correct fuel and air metering on 120SR engines.

Installation normally requires disassembly of the carburetor, inspection of gaskets and needle parts, and careful reassembly with correct screw torque to avoid air leaks. Check the throttle shaft, linkage travel and sealing faces before final fitment.

For tuning and maintenance the body serves as the replacement chassis for the carburetor internals, enabling worn housings to be swapped without changing jets or needles. Confirm mounting point alignment and throttle clearance against the engine before conducting fuel runs.

The listing is for the carburetor body only; ensure compatibility with your engine model prior to purchase and adhere to standard RC nitro engine safety practices during installation.
