Throttle Return Springs
Stop throttle creep!
A common complaint about the Rotax 912/914 engines is that the throttle return springs are too strong. McFarlane stocks a variety of springs so you can choose the one that best fits your application. All McFarlane throttle controls for Rotax engines include P/N 7140 springs.
Unique hook design for left and right applications provides for better fit and retention.
