Why does my Briggs and Stratton engine cut out?
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.
What are the symptoms of a blown head gasket in a lawn mower?
If the mower is dropping out or not starting and you do notice the oil leak, you have a bad gasket. If the mower shuts off when you turn corners, but there is no oil leak, you may still have a bad gasket since the pressure to keep the combustion going is not strong enough.
What happens when a lawn mower overheats?
An overheating engine can cause components to seize up or, in extreme cases, engine combustion. The primary cause behind engine overheating is a dirty engine. Dirt and debris can get into the vents and block the air intake, meaning that cool air cannot flow over the engine and cool it.

Why does my lawn mower dies when it gets hot?
A simple, often overlooked, trigger for an engine stall occurs when the heated gases inside the fuel tank can’t vent properly. The pressure causes the gas flow to reverse and move out of the carburetor, effectively shutting the engine down. On lawn mowers, most vapor lock occurs through a dirty fuel tank cap.
How do I know if my lawnmower is overheating?
Another symptom of an overheated mower engine can be that it will lock up or shut down, which might be a good thing because it will prevent further damage but also might be a sign of some damage itself.
What causes vapor lock in lawn mowers?
Vapor lock generally occurs when the fuel (usually gasoline) within the fuel delivery system overheats and vaporizes too rapidly. The resulting excess gas bubbles accumulate to the point of actually blocking normal fuel delivery.
Can a bad spark plug cause a mower to stall?
Poor Engine Performance
After the engine finally begins to start, it may tend to die out immediately if something is wrong with its spark plug. In some cases, the engine may run for a while then stop while mowing. A bad spark plug also may cause misfires, with the engine sputtering, missing or popping.
How do I stop my lawn mower from sputtering?

- Remove the cap of the gas tank and look in at the gas.
