K&S KS23751 Engine Needle Extension Rod (Blue)  [KS23751]

Needle extension for RC glow engines

This K&S KS23751 engine needle extension rod is an RC-scale replacement part intended to extend the carburetor needle for easier access during engine tuning. The piece is supplied in blue anodized finish and is designed to assist with mixture adjustments without requiring changes to the carburetor body or engine mounting position.

Use it when you need clearer access to the high speed or low speed needle during on-track tuning or bench setup. The extension provides a simple mechanical link from the engine needle to your accessible tuning area so you can make fine adjustments while the model is running or idling, keeping the adjustment point visible and reachable.

Installation is straightforward: integrate the rod into the existing carburetor linkage following the engine or carburetor manufacturer's guidance, secure any original fasteners, and verify free movement before running the engine. Avoid forcing the linkage and perform adjustments incrementally to maintain safe needle settings for your RC glow engine.
