A lawn mower motor is a fairly simple machine. Like all petrol engines, you need fuel, air and a spark. A piston compresses the gasoline into a cylinder. A spark then ignites the gasoline, and the explosion pushes the piston down the cylinder to rotate a shaft that moves the mower blade. Like all petrol engines, a lawn mower can develop problems. A landlord can determine and solve many of these.
Instructions
1 Check the air filter for the first time on an engine that starts and dies; Lack of air is the most common cause. Remove the screw that holds the top of the filter compartment, which is usually on top of the carburetor, with a screwdriver and inspect the filter. Wash a foam filter in lukewarm water and soap if it is dirty, covered with oil and dust. Replace it if it is not going to wash clean. Replace a dirty paper filter.
2 Troubleshooting the spark plug. First, check that the spark plug wire is making a good connection to the Plug and is not loose. Use a spark plug wrench to unscrew the plug. Check the electrode at the bottom; If it burns or heavily soiled with oil or charcoal, replace the cap. Make sure the new plug has the right space on the electrode.
3 Proof of gasoline, which can go wrong in a lawnmower tank, especially if you have been left seated for a while. Empty the tank if there is any doubt; Put the gas age in your car, where it burns without problem. Fill the tank with new gasoline. Use gas without an alcohol additive if the engine is hiccups or detonations before it dies.
4 Clean carburetor. First remove the air filter compartment and spray a carburetor cleaner from the car into the carburetor barrel. Spray the throttle and choke linkage on the outside of the carburetor to dispose of any grease or dirt that may hinder the proper operation.
5 Inspect under mower. Clean up any sludge or grass clippings that may be preventing the blade from spinning, exerting undue pressure on the motor. Make sure the blade can rotate freely during operation. Remove the spark plug cable for safety when inspecting the blade.
6 Look at the muffler to make sure it does not stop until; An engine that will exhaust the burnt gases to perform properly. Clean the muffler or replace it if it is damaged and will not allow air to flow freely. Finally, check the control bar on the mower handle, which should be pressed to start the engine, to ensure that it is working properly; Examine the linkage with the engine to make sure it is connected.
