McFarlane offers two styles of choke control for the dual carburetor Rotax 912/914 series engines:
Turn-to-Lock Style Choke Controls:
These controls feature a turn-to-lock mechanism that requires a quarter turn of the knob to lock or unlock the control at any position.
Go to Turn-to-Lock Choke Controls for more details.
Non-Locking Choke Controls:
These controls do not feature a locking mechanism, however they have an internal elastomer seal to dampen vibration and provide a small amount of resistance. If your choke installation features a return spring, this control will return to the closed position when released.
Go to Non-Locking Choke Controls for more details.
These controls are not for use on certified aircraft.
