Fixing Weed Eaters

Ensure that fuel or power is being supplied to the weed eater. If it's fuel operated, make sure you have the proper gas-engine oil mix. If your mixture isn't correct according to the manufacturer instructions, dump the fuel and remix it. Make sure you've primed the engine before starting it; this is usually a soft button located close to the motor, and you may need to press it several times to start a cold motor. If your weed eater is electrical, make sure it's plugged in and the plug hasn't been damaged or corroded. Make sure the power switch is on.

Check all fuel lines, electrical wires and other components on the weed eater. Make sure there's no fuel leak. Replace any leaky or broken components.

Locate the spark plug and replace it. A new spark plug only costs a few dollars at the hardware or automotive store, and replacing it is quick and easy.

Change out the air filter. Filters start out white or light-colored, so if yours is black, it's too dirty to allow the engine to work properly.

Take your weed eater to an authorized service center and have a professional inspect it. You may need to have your carburetor adjusted, or another technical problem may need correcting.
