Choke Valve - Lifan KP4500iE Owner's Manual

5.5 Choke Valve

The choke is designed to restrict the air flow to the
carburettor, providing a richer fuel mixture which enables
the engine to be started easily in cold conditions.
When starting from cold, select the "CHOKE" (start)
position on the 3 in 1 control knob.
Once running and engine is warm, set and leave the 3 in 1
control knob to the "RUN" position.
