🔌 Function

Provides the return load that pushes its component back against its seat or stop, so the part it sits behind closes cleanly instead of drifting.

⚠️ Common Signs of Failure

• Uneven or hunting idle
• Spring collapsed or noticeably shortened, having taken a set
• Cracked or broken coil found on strip-down
• Corrosion or varnish build-up on the coils
• The part it loads no longer returning fully to its rest position

🛠️ Service Notes

• A spring that has taken a set will not recover, so renew rather than refit it
• Check the seat and bore the spring works against while the assembly is open
