This YS Engine needle socket pack serves as a practical RC spare to keep needle components separated and easy to find during tuning and maintenance work.
The box contains 50 pcs needle sockets intended to hold and protect single needles or small needle assemblies, helping to avoid loss and keeping multiple needle choices accessible when setting carburettor mixtures.
Supplied as a branded spare, it is meant to be used with YS Engine parts and other compatible RC engine needle components, supporting on-bench organisation rather than providing performance gains.
Storage advice: label each socket by needle or setting, keep them away from moisture, and handle small parts with tweezers to prevent dropping them.
