Understanding the Role of the Choke Lever in a Champion 43cc Tiller
What Does the Choke Lever Do?
The choke lever on a Champion 43cc tiller is a vital component that manages the air-fuel mixture entering the carburetor. During cold starts, the choke restricts airflow, enriching the fuel mixture to facilitate easier engine startup. Once the engine warms up, the choke lever should be moved to the open position to allow optimal airflow for normal operation.
