Understanding the Importance of a Carburetor

When I first got my Yamaha Big Bear 400, I quickly learned that the carburetor plays a crucial role in the engine’s performance. It mixes air and fuel for combustion, which directly impacts how well my ATV runs. A well-functioning carburetor ensures that my ride is smooth and powerful, while a faulty one can lead to poor performance and frustrating stalls.
