Additional information
This extension spring, part number 722423, applies controlled tension to linked components so levers and mechanisms return to their intended positions during operation. Proper spring tension helps controls respond smoothly and consistently.
If controls feel loose, do not return fully, or fail to hold position, the extension spring may be stretched, weakened, or broken. Visible elongation or missing tension can also affect how the mechanism operates.
Before starting the repair, disconnect the spark plug wire to prevent accidental starting. Extension springs are under tension; use pliers or a spring tool and keep your hands clear while installing the spring to avoid injury.
