How do you replace recoil spring on a weed eater?

To replace the recoil spring on a weed eater, first, ensure the engine is off and remove the spark plug for safety. Take off the recoil starter cover by unscrewing the screws holding it in place. Carefully remove the old recoil spring and install the new spring, ensuring it is properly seated in the housing. Finally, reassemble the recoil starter cover and reattach the spark plug.
