YS Engine YSS2049 High Speed Needle Socket 56SR - high-speed needle socket for RC engine needle tuning  [YSS2049]

High-speed needle socket for RC engines

This YS Engine YSS2049 high-speed needle socket is an RC-scale accessory intended to hold and secure the high-speed needle during tuning and service of model engines. It focuses on delivering a stable coupling between the fuel mixture needle and the carburettor linkage so adjustments can be made consistently without slippage or damage to the needle tip.

Installation is straightforward: seat the needle into the socket so the needle tip aligns with the carburettor needle seat, then tighten gently while checking for smooth rotation and repeatable movement. The socket is intended to assist in fine tuning the high-speed needle setting by providing a consistent interface between the tuning tool and the needle assembly.

Tuning role: use the socket to make incremental adjustments while the engine is running on a test stand or during controlled bench checks, observing the needle response and engine behavior. The design emphasizes repeatability and a secure grip to reduce the risk of rounding or slipping during adjustment, keeping all descriptions within RC model engine use only.
