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

Needle-valve extension cable overview

This needle-valve extension cable set is presented as an RC-scale accessory intended to provide remote access to the carburettor needle on model engines. It is intended to assist builders and tuners who prefer or require an externally reachable needle control without repeated disassembly of the model.

Use and compatibility: the set is suitable where a need exists to relocate needle access points to a convenient external position on the model, for trimming fuel mixture or idle while the engine remains mounted. Confirm physical routing and clearance on your model before fitting to ensure the cable can follow a safe, unobstructed path.

Installation and tuning role: install by routing the cable from the carburettor to the chosen external access point, secure it to prevent chafing or kinking, and verify smooth needle movement before running the engine. During tuning the extension allows incremental needle adjustments from outside the model, reducing the need for repeated shutdowns and partial disassembly.
