How to Adjust the Carburetor on a Homelite Weed Trimmer
- 1). Turn on the Homelite's engine. Run the engine at a high idle for at least 10 minutes to obtain the proper operating temperature. Locate the carburetor adjusting screws, located between the air filter and the engine on the carburetor. The high and low speed screws will have plastic limiter caps on them.
- 2). Locate the low speed screw, or the screw to the left. Turn this screw clockwise, noting the effect on the engine. Turn the screw back counterclockwise, noting the effect on the engine. Locate the point in between these two settings that achieves the best running sound.
- 3). Locate the idle speed screw, just above the low and high speed screws. Turn the screw clockwise until the trimmer head starts to spin. Back off the screw slowly until the head stops spinning.
- 4). Locate the high speed screw, or the screw to the right of the low speed screw. Turn this screw counterclockwise until it cannot be turned any more. Make any adjustments to the low and idle screws as necessary after the high speed is adjusted.
