Make sure that the weedwacker fuel tank is filled with

fresh

gas having the proper mixture of oil/gas. If the gas is over 30 days old and fuel stabilizer was not used, I recommend that you replace the fuel in the tank of the weedwacker.

To get the correct oil and fuel mixture follow the steps below:

Most 2-cycle products come with a 3.2 ounce bottle of oil. Add that 3.2 ounce bottle of oil to one gallon of clean fresh gasoline to achieve the 40 to 1 gasoline and oil mixture.

Use fuel stabilizer in fuel to maintain freshness. Follow the directions for mixing and use that are on the container.

A dirty or defective spark plug will not provide the proper spark to ignite the fuel mixture. A spark plug must be clean and have a proper gap between the electrode and ground for proper engine operation. Remove the spark plug and check it as shown in the image below. Check your owner's manual for the proper gap setting. If you don't have your owner's manual, you may be able to find it online using our Manage My Life owner's manual search tool.

Two cycle weedwackers have a fuel filter (fuel pick up) in the gas tank that should be changed periodically or when plugged. Here is a procedure for changing the fuel filter:

Empty the fuel tank using a siphon kit, available at Sears, (71 33119) or by removing the fuel line from the carburetor and drain the fuel into an approved safety container (Typically a red gas can labeled "Gasoline").

Locate gas line in tank with filter on the end.

Carefully lift filter out of tank with fuel line attached. (see 2nd image below)

Remove filter from line.

Install new filter in the line.

Reinstall line and filter into tank.

Refill fuel tank with the correct gasoline oil mixture.

You could be flooding the engine when you prime it. Wait for a few minutes before attempting to start it when it does not start the first time.

A problem with the gas cap vent could also prevent the weedwacker from starting. Clean the vent on the gas cap if necessary.

If these tips don't help, you weedwacker will likely need service by a technician. Here is a link for the Sears Service website that has drop-off locations and service information:
