A lawn mower will not start if the fuel is contaminated or old
Fuel can start to break down and become less effective as soon as 30 days after purchase. It is possible for ethanol left over in your fuel and moisture in your fuel to clog your fuel system, including your fuel lines, fuel filter, and carburetor.
It is recommended to add a fuel stabilizer after you have not used your fuel for 30 days. This should be added to the fuel you run in your fuel tank as well as any gas remaining in your storage tank.
It is necessary to remove the old fuel. Added fresh fuel will flush the tank. To clean and stabilize the fuel system, add a fuel additive. An item called Sea Foam Motor Treatment has worked well for me. Here are more details on why I use Sea Foam.

The lawn mower fuel cap needs to be cleaned.
As you make the first few passes with the mower, the mower suddenly stops. Pull the cord a few times, but the engine just sputters and dies. How is this happening? A fuel cap could be to blame. Most mowers have vented fuel caps. Fuel flows from the tank to the carburetor through this vent as it releases pressure. Fuel flow ends when a vacuum is created inside the tank as a result of gas fumes building up inside.
Remove the gas cap in order to break the vacuum, then reattach it to see if this is the issue. When you turn on the mower, it should start right up. A replacement gas cap will be needed if your lawn mower doesn’t stay running after 10 minutes or so.

A lawn mower that sputters and dies after repeatedly pulling the starter cord can be extremely frustrating and backbreaking. If you find that the lawn mower needs repairs, you may be inclined to take it to a repair shop or even leave it outside for bulk trash pickup.
