How does this replacement affect performance and maintenance?

A properly fitted carburetor restores consistent fuel delivery, making starting easier and smoothing out idle and throttle response.

Regularly inspect fuel lines and use fresh gasoline to keep the new carburetor operating well.

• Improves starting reliability and idle stability
