McFarlane Control Choke Dual 12Foot Round Black Knob MCC101D144-RBC

McFarlane Aviation MCC101D144-RBC is a non-locking dual choke control with a 3.66 m (12 ft) conduit and a round black knob engraved “CHOKE”. It is designed by the manufacturer for dual-carburettor Rotax 912/914 series engine choke installations, providing a clean dual-control routing without a splitter box.

The all-metal control uses a high-temperature PTFE-lined conduit for smooth operation. An internal elastomer seal provides vibration damping and light operating resistance; where the installation incorporates a return spring, the control returns to the closed position when released.
