Plus it wastes fuel! Of course, too little is just as bad... I've always gone for the following, though I don't know if it's ...

The choke is a tool to allow a cold engine to run by enriching the fuel/air mix through restricting (or choking) the air supply - once the engine is warmed up, this is not needed any more. ...

Gasoline getting in the oil past the piston rings due to being over rich too long and and causing pre-mature engine wear and lower compression due to the ...

How the choke works The choke of a scooter consists of a dedicated choke nozzle in the fuel reservoir and two narrow drillings leading to the venturi (the pipe where the air goes through): When the motor cranks and the choke is active, the slight underpressure in the venturi sucks in extra fuel through this drillings. When the choke is inactive, a ...
