Needle-valve Extension Cable for Model Engines O.S. Engine OS72200080  [OS72200080]

Remote needle-valve extension overview

This O.S. Engine OS72200080 needle-valve extension cable set is an RC accessory that gives remote access to the carburettor needle on model engines, allowing adjustments without dismantling the model.

Fit and compatibility: the kit is intended for situations where relocating needle access to an external point improves convenience for trimming fuel mixture or idle while the engine remains mounted. Always verify routing space and clearances on your model before fitting to ensure the cable can be installed without obstruction.

Installation and tuning role: install by routing the cable from the carburettor to your chosen external access point, secure it to prevent chafe or kinking, and check for smooth needle movement before running the engine. With the extension fitted you can make incremental needle adjustments from outside the model, cutting down on repeated shutdowns for access.
