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.

• New design limits potential contact with adjacent parts

• Less than half the strength of the original stock Rotax springs
• Tailored for Rotax engines, including the Vans RV-12 aircraft
• Prevents throttle "creep" due to excessive return spring force
• Requires 1 per carburetor (2 per engine)

Note: Installer is responsible for determining whether this spring is an appropriate substitution for their application. For use on non-certified aircraft.
