🔌 Function

The spring keeps the throttle and spark-advance components under controlled tension. It helps the linkage follow the cam accurately and return toward the idle or retarded position when throttle input is reduced.

⚠️ Common Signs of Failure

• Spring is stretched, broken or permanently distorted
• Linkage does not return smoothly to idle
• Throttle or spark-advance lever rattles or has excess free play
• Engine speed remains elevated after the control is reduced
• Corrosion weakens the spring or causes binding
