What can I do about a lawn mower that won't crank?

Answer by  mbmb (12)

First of all check the fuel level. After several attempts to start the engine, sparkplugs can be too wet and waiting a few minutes before trying again may already solve the problem. Altering the engine's speed level (slow, medium, high) will change the mixture of fuel and oxygen and will help to start the engine.

Four things will keep an engine from starting: lack of fuel, lack of air, lack of fire (spark), or failure to turn. Thus, check that the air filter is unobstructed, that the carburetor isn't clogged, rebuild the carburetor if necessary, check that the spark plug isn't fouled and that the system produces spark, and that the engine turns freely.

It could be several things. Your gas might not be any good or properly mixed. Also spark plug might need to be replaced.

Make sure that your battery is charged and cables are connected good first. if it wasnt that remove the carburetor and clean it by soaking it in a cleaning agent(deisel,enginecleaner,...).

When lawnmowers sit unused during the winter months, they get build up on the spark plugs. Try changing your spark plugs, changing or adding oil and make sure that you have gas in it.
