Leaving the choke on while operating will result in excessive fuel consumption, irregular engine power performance and eventually may even damage the engine. This allows for more fuel to be used, which in turn helps the engine to spark and ignite easier. Then if you move the choke to the run position (opening the choke valve), the engine accelerates. Keeping the choke engaged after this stage is very bad for your lawnmower’s longevity, as well as your wallet. DO NOT ride it with the choke on.
