Common Troy-Bilt gas line trimmer replacement parts

• Air filter. An air filter is an absorbent foam rectangle that's mounted on the air intake to the carburetor. It filters the air that enters the carburetor to mix with the fuel.
• Carburetor rebuild kit. The carburetor rebuild kit contains the essential components such as diaphragms, seals and gaskets needed to tear down a carburetor and rebuild it so it works properly.
• Fuel lines. Fuel lines are made of flexible tubing that carries fuel from the tank to the carburetor and from the primer bulb to the fuel system.
• Cutting line. The cutting line that is initially installed in the cutting head of the trimmer will eventually be used up. Replacement cutting line is available in various sizes. Replace the cutting line with the proper size for your grass line trimmer.

How to troubleshoot your Troy-Bilt gas line trimmer when it runs rough

If the fuel has been in the tank unused for months, it can pick up moisture and fail to ignite (that's why you should drain the fuel before storing for the winter or add fuel stabilizer to the tank). Replace the fuel with fresh gas if it's old and untreated with stabilizer. You might also need to replace the fuel filter at the same time. Performing preventive maintenance including a line trimmer tune-up will also help the engine run smoothly.

Check the fuel lines for cracks and replace them if necessary. If you still have problems after checking those issues, consider replacing or rebuilding the carburetor.
