Clean Air Filter

• The air filter regulates the air system and sits above the carburetor. Before any air can enter the engine, it passes through a foam filtration system, housed inside the air filter. This dust and debris will get trapped in the filter and eventually clog up completely if it’s not cleaned regularly. The air filter on a Featherlite needs to be cleaned after every 10 hours of operation. Wash the filter in a mild detergent, like dish soap, and rinse it under cool water when finished. Leave it out to dry before reusing it.
  
  

Check Fuel System

• The fuel originates in the tank, travels up the fuel hose and into the carburetor. If the fuel can’t pass from the tank into the carburetor, the engine will shut off. If the Featherlite has an idling problem, it may be due to a small loss in fuel as it passes through the hose. Cracks, leaks and other damage to the hose can cause a loss in fuel that forces the engine to die when idling. Empty all the fuel from the tank into an approved fuel container. Pull the fuel filter out of the tank, and wash it in the soapy water as well. Examine the hoses for any damage, and replace if necessary.
  
  

Add Fresh Fuel

• Sometimes just adding freshly mixed gas will make the trimmer run a whole lot better. Since the Featherlite uses a two-cycle engine, it needs a mixed fuel that combines engine oil with gasoline. This fuel will start breaking down and destabilizing after 30 days. When this happens, the fuel will start gumming up and sticking to the tank, fuel filter, fuel hose and carburetor. Weed Eater recommends using an air-cooled two-cycle engine oil combined with 87 octane fuel at a ratio of 40:1.
  
  

Adjust the Carburetor

• Every carburetor on Weed Eater products, including the Featherlite, operates with a speed adjusting screw, which regulates the intake amount of fuel at the engine’s idle speed. Adjusting this screw will allow the operator to increase or decrease the amount of fuel at idle speed. However, this screw should only be adjusted after the air filter has been cleaned, the fuel system has been checked, and fresh fuel has been added. Adjust the screw until the head starts to spin, then turn the screw back to the highest rpm before the head starts spinning.
