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

What this needle extension does

The O.S. Engine OS72200080 needle-valve extension cable set is an RC accessory that moves the carburettor needle control to an accessible external position so tuners can make quick adjustments while the engine stays installed.

Use and fitment guidance: the kit is suited for applications where external access to the needle improves tuning efficiency. Before fitting, plan the cable route and check for sufficient clearance to avoid interference with other components.

Installation and adjustment workflow: feed the cable from the carburettor to your chosen access point, anchor it to prevent friction or sharp bends, and confirm smooth needle action prior to operation. This arrangement reduces the need to stop and partially strip the model to alter mixture or idle settings.
