Frequently Asked Questions

Q: Why is a high-tension throttle return spring important for kart racing?

A: A high-tension spring ensures the throttle lever returns to the idle position instantly when you lift off the pedal. This provides a predictable, snappy response that helps you maintain better control during aggressive cornering and prevents the engine from hanging at high RPMs.

Q: Is the Tillotson 24B-381 spring compatible with all Tillotson carburetors?

A: This spring is specifically designed for Tillotson applications requiring the 24B-381 specification. Always check your carburetor model or original parts manual to ensure compatibility with your specific linkage setup.

Q: How do I know if my throttle return spring needs to be replaced?

A: If you notice your throttle feels "mushy," slow to return to idle, or if the spring shows signs of stretching or fatigue, it should be replaced immediately. A weak spring can lead to inconsistent lap times and safety issues on the track.

Q: Can this spring help with wheel spin on corner exits?

A: Yes. By providing a consistent and predictable throttle return, this spring allows for smoother, more controlled power application. This helps you manage your power delivery more effectively, reducing the likelihood of unwanted wheel spin when exiting a corner.
