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.

If your lawn mower starts, runs briefly, then dies these are the four most common reasons that`s happening: Dirty carburetor / clogged carburetor bowl. Old gasoline that has gone bad. Dirty or defective spark plugs.
Q. Why is my lawn mower turning over but not starting? The most likely reason is bad gas. Gas that sits for many months during the off-season will eventually break down, gumming up the fuel line and carburetor in the engine and preventing it from starting.
A clogged carburetor is most commonly caused by leaving fuel in the lawn mower for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall.
If your lawn mower starts, runs for a while, then dies, check the ignition coil, gas cap, and spark plug. One or more of these parts could be causing your problem. Follow our repair and symptom guide to help you fix this.
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.

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.
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.

Other things that could cause this issue are bad fuel, weak/colapsed/kinked fuel line, faulty spark plug, faulty ignition/coil, oil over full, clogged air filter, plugged/dirty carburetor, worn engine parts internal rings/valves/etc.
