3. Locate the carburetor. It is usually mounted on the side of the engine.
4. Remove the carburetor float bowl. This is a metal bowl that sits at the bottom of the carburetor. It is held in place by a few screws or bolts.
5. Remove the carburetor needle. The needle is a small, metal rod that sits inside the float bowl. It is held in place by a spring.
6. Adjust the needle. The needle can be adjusted by turning it clockwise or counterclockwise. Turning the needle clockwise will lean out the fuel mixture, while turning it counterclockwise will richen the fuel mixture.
7. Reassemble the carburetor. Install the float bowl, air filter, and air filter cover.
