YS Carburettors FZ115S Needle Socket for Needle Seating - YSG2062 by YS Engine  [YSG2062]

FZ115S needle socket overview

This YS Engine YSG2062 needle socket FZ115S is an RC-scale replacement part made to accept FZ115S-type carburettor needles used in YS carburettors. It functions as the needle seat and retainer, locating the needle tip and helping to keep needle position consistent for dependable tuning.

Fitting is uncomplicated for anyone comfortable with small glow-engine carburettors: follow the engine manual to remove the needle assembly, place the socket into the needle holder or onto the needle as required, and reassemble the carburettor making sure the needle travels freely. Only standard hobby hand tools are normally needed.

In service this socket stabilizes mixture control by preserving needle alignment after repeated adjustments or maintenance. Swapping a worn or damaged needle seat for this socket restores predictable seating so idle and mid-range settings respond reliably.
