A Dirty Carburetor Can Cause a Lawnmower To Start Then Die
By far, the most common issue that causes a stalled motor is a dirty carburetor. The carburetor on your engine is the thing that draws in air and mixes it with the fuel. Contrary to what the movies might make you think, gasoline itself is not very flammable.
Disconnected, dirty or fouled spark plugs are common causes for engines that won`t start. For small engines, spark plugs typically need to be replaced every season or after 25 hours of use. You should also check to make sure the spark plug gap is set correctly.
Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas. If this doesn`t work, you might need a new fuel filter.
A dirty carburetor is the most common cause of a lawn mower that starts and then dies. Other possible causes include: Stale/Dirty Gas. Faulty Choke.
Your lawn mower runs for 30 minutes then dies if you are having issues such as a bad spark plug, air problems, a malfunctioning carburetor, or a faulty gas cap. You may even encounter the issue that your lawn mower runs for 5 minutes then dies.
Electric lawnmowers may cut out for two main reasons: A faulty power switch or a loose cable connection. An overheating motor can cause the thermal cut out to trip.
The most likely cause of a no-start mower after running out of gas is dirt in the carburetor, but other possible causes include: Air locked gas system. Faulty carburetor. Contaminated gas.
Why Is My Lawnmower Turning Over But Not Starting? If you pull the cord and hear your engine turn over, but your mower is not starting, the most common reasons for this are low fuel, a broken gas valve, or a bad choke fault. A broker spark plug could also be the culprit.
Common reasons for your lawn mower turning over but not starting can include low oil levels, dirty air filter, faulty spark plug, stale fuel, clogged carburetor, dead battery, broken gears and clutch, or faulty ignition coil. Problems with the air, fuel, and spark supply systems are usually to blame.
The spark plugs are worn or damaged
If you find that your lawnmower keeps dying, or keeps stalling while cutting grass, then inspect the spark plugs. Look for signs of damage or wear. Something as simple as a cracked porcelain insulator can mean an electrode has been damaged or burned away.
Use Carburetor Cleaner
Fortunately, you can generally do this without even taking the carburetor out of the engine. Start by purchasing some commercial lawnmower carburetor cleanerOpens a new window, which comes in a simple spray can and will make it easy to clean the inside and outside of the carb.

Self propelled mower will start but want stay running long? it runs about 3 or 4 min. then stop and when i restart it, it will start back up.
ANSWER : The fuel bowl has a float and needle, if the float isn’t floating to open the needle for gas to flow into the carb, it will cut off. A kit can be purchased for about $5 or take yours out and soak and clean then replace. Usually when these go bad its best to replace them.

Pump works for about 20 seconds then stops for 40 seconds then starts again.
ANSWER : This sounds as if motor is overheating and the thermal switch is stopping it (why it restarts by itself) if a pump is overheating then a few reasons need be looked at , is pump encountering higher viscosity’s than designed for and is having trouble moving liquid fast enough , is distance pump has to lift liquid over what it’s designed to do most of these pumps use liquid it’s moving to provide cooling to pump , is liquid it’s moving warm/Hot allready if so use different type of pump (non submerged) and last but not least is pump worn out and is failing moving parts wearing together make heat !!! ?
