YS Engine YSS2049 High-Speed Needle Socket 56SR Compatible RC Needle Tuner  [YSS2049]

Engine tuning socket for consistent needle control

The YS Engine YSS2049 high-speed needle socket is an accessory for RC model engines, designed to secure the high-speed needle while performing tuning and maintenance. It concentrates on ensuring a steady engagement between the fuel mixture needle and the carburettor linkage so that settings can be changed reliably without causing tip damage or slippage.

To fit: place the needle in the socket so that the tip seats correctly against the carburettor needle seat, then tighten with care, verifying smooth rotation and uniform movement. The socket offers a dependable interface between the adjustment tool and the needle assembly for improved tuning precision.

When tuning, make slow, measured adjustments with the engine running on a test rig or during careful bench checks, watching the engine response closely. The construct emphasises repeatability and a secure hold to minimise rounding or slipping during adjustment, and is described solely for RC model engine use.
