What is the function of a choke on a lawnmower engine?
A choke on a lawnmower engine, or any engine with a carburetor, is a device that reduces the airflow through the carburetor. It causes the fuel-air ratio to be richer, that is, more fuel and less air. This helps most carbureted engines to start while cold and before steady fuel flow is established, but the rich mixture reduces the power and efficiency of the engine tremendously. Leaving the choke on will produce hydrocarbon and carbon monoxide emissions and may cause the engine to stall as soon as any load is placed upon it. That is why engines require either manual release of the choke or have an automated device to back it off. Excessive use of the choke will generally result in fouled spark plugs.
Will fouled spark plugs couse a Chevy 350 not to crank after cleaning the carb?

Fouling spark plugs can happen when the tip temperature is insufficient to burn off carbon, fuel, oil or other deposits and causes spark to leach to metal shell...no spark across plug gap will cause a misfire.
