K&S KS23751 Engine Needle Extension Rod (Blue) - RC Tuning Access  [KS23751]

Needle extension for precise tuning

This K&S KS23751 engine needle extension rod is designed as an RC-scale replacement to lengthen the carburetor needle linkage and provide improved access for tuning. The part is finished in blue anodized aluminum and helps with mixture adjustments while leaving the carburetor body and engine mounting unchanged.

Use the extension when clearer access to the high-speed or low-speed needle is required during bench or trackside tuning. The rod delivers a simple mechanical connection from the engine needle to a reachable point so you can perform fine adjustments while the engine is running or idling.

Fitting is straightforward: connect the rod into the existing carburetor linkage following the engine or carburetor instructions, refit any original fasteners, and confirm free movement before operating the engine. Avoid forcing the linkage and make incremental adjustments to preserve safe needle settings for your RC glow engine.
