This YS Engine needle socket pack is an RC-scale spare intended to keep needle components organised during maintenance and tuning tasks.
The pack contains 50 pcs needle sockets designed to hold and protect individual needles or small needle assemblies, helping to prevent loss and making it easier to keep multiple needle options at hand while adjusting carburetion settings on model engines.
As a branded spare, it is supplied for use alongside YS Engine parts and other compatible RC engine needle components, serving a practical role in parts rotation and on-bench organisation rather than as a performance upgrade.
Practical tips: label sockets by needle size or setting, store in a dry place, and handle small parts with tweezers to avoid misplacement.
