What is this part & what does it do?
A carburetor assembly regulates and mixes fuel and air before it enters the engine combustion chamber. Proper fuel-air mixture is essential for starting, throttle response, fuel efficiency, and overall engine performance. A worn or malfunctioning carburetor can cause hard starting, poor performance, or engine failure. Replacing it restores proper engine operation.
