YS Engine YSS2049 High Speed Needle Socket - 56SR, RC Carburettor Needle Tool  [YSS2049]

Precision socket to stabilise carburettor needles

The YS Engine YSS2049 high-speed needle socket is created for RC enthusiasts who need a steady method to hold the high-speed needle while tuning or servicing model engines. It helps maintain a strong connection between the fuel mixture needle and the carburettor linkage, reducing slippage and protecting the needle tip during adjustments.

To install, position the needle into the socket so the tip seats correctly against the carburettor needle seat, then tighten carefully while ensuring smooth rotation and reliable movement. The socket offers a uniform contact point between the tuning tool and the needle assembly to improve the quality of fine adjustments.

For tuning use: perform small, controlled changes while observing engine response on a test rig or during careful bench tests. The item is designed to prioritise repeatability and secure gripping to lower the chance of rounding or continual slipping while adjusting, and is intended for model engine use only.
