How To Adjust Carb On Stihl Weed Eater?

The carburetor on a Stihl weed eater is responsible for mixing the fuel and air in the correct proportions to create a combustible mixture. If the carburetor is not adjusted properly, the weed eater may run too rich or lean, which can lead to decreased performance, poor fuel economy, and even damage to the engine.

Adjusting the carburetor on a Stihl weed eater is a relatively simple task, but it is important to follow the steps carefully to avoid making any mistakes.

Tools and Materials

• Phillips head screwdriver

Step 1: Turn Off the Weed Eater and Let It Cool

Before you begin adjusting the carburetor, it is important to turn off the weed eater and let it cool down. This will help to prevent burns and injuries.

Step 2: Locate the Carburetor

The carburetor is located on the side of the engine. It is a small, black box with a number of ports and valves.

Step 3: Remove the Air Filter

There are two adjustment screws on the carburetor: the idle speed screw and the main jet screw. The idle speed screw is located near the top of the carburetor, and the main jet screw is located near the bottom.

Step 5: Adjust the Idle Speed Screw

Use the Phillips head screwdriver to turn the idle speed screw clockwise to increase the idle speed, or counterclockwise to decrease the idle speed. The idle speed should be set so that the engine is idling smoothly without any hesitation.
