🔌 Function

The spring provides calibrated resistance within the governor linkage to control engine-speed response.

⚠️ Common Signs of Failure

• Engine speed hunting
• Incorrect rated speed
• Poor response to load
• Spring stretched, broken or corroded
• Incorrect installation position

🛠️ Service Notes

• Compare the new spring with the old for free length, wire diameter and number of coils before fitting; springs that look alike often have different rates
• Never stretch, shim or cut a spring to change its behaviour, and never refit one that has taken a set, is pitted, or shows a bright rubbed patch from coil clash
• Where springs work as a set, renew the whole set together so the loading stays even
• Fit the spring the way it came out where the ends or the coil pitch differ from one end to the other, and make sure it seats fully in its locating step or pocket
• Keep the spring and its seat clean and check for corrosion — a corroded spring in a fuel or engine assembly is a broken spring waiting to happen
