Needle socket for FZ115S carburettor

This YS Engine YSG2062 needle socket FZ115S is an RC-scale replacement part intended for use with FZ115S-type carburettor needles on YS carburettors. It serves as the needle seat/retainer that locates the needle tip and helps maintain repeatable needle positioning during tuning and service.

Installation is straightforward for anyone familiar with small glow-engine carburettors: remove the carburettor needle assembly according to the engine manual, fit the socket to the needle or needle holder as required, and reassemble the carburettor ensuring the needle moves freely through its travel. No special tools are required beyond typical hobby hand tools.

Functionally this part supports mixture control by keeping needle alignment consistent after repeated adjustments or maintenance. When swapping worn or damaged needle seats, replacing this socket restores predictable needle seating so idle and mid-range tuning respond as expected.
