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.
There may be old or bad fuel in the carburetor float bowl. 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 prevent the engine from starting. If the carburetor is clogged, try cleaning it with carburetor cleaner.
Touch the metal shaft of a screwdriver to both of the large terminals at the same time. If the engine turns over and starts, the solenoid is bad and should be replaced. If the starter motor does not run, the motor itself is probably defective.
Solenoid Valve Does Not Open or Close
Thoroughly examine the power supply. Ensure that the voltage, current and frequency are correctly supplied to the valve. Check the connections and make sure they are properly installed. If there is any dirt or corrosion in the diaphragm, safely clean it.
As the fuel level drops, a vacuum begins to form in the fuel tank because air can get in to fill the space the consumed fuel occupied. After about 10 or 15 minutes, the vacuum will become strong enough that fuel will stop flowing to the carburetor and the lawnmower will die.
The most common reason for a surging lawn mower engine is a blockage in the fuel supply, but there are other possibilities: Bad gas. Bad spark plug. Dirty/faulty carburetor.
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.
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.
The advent of start/stop technology for internal combustion engines is straining the lifespan of existing starter solenoids. In a typical combustion engine application, a starter solenoid may undergo approximately 30,000 actuations over a 15-year vehicle lifespan.

Mower won’t start
ANSWER : This may sound stupid but don’t mean it to…
Have you tried with the choke all the way open? Do you have an automatic cruise? Is the right (correct) pedal being pushed in? These will affect if it starts or not. Also if your drive belt or one of the other belts not being tight enough will affect if it starts or just turns over. Not too many things can stope it from starting with new/good battery AND if its getting gas. Try cleaning your gas line and obviously making sure there is no obstruction around or near your blade, if it does start with blade engaged that is :))
If it doesn’t start with blade engaged, well make sure it’s in neutral. Mine won’t start in reverse but will in forward or neutral.

Mower starts runs begins to back fire and run
ANSWER : Sounds like it is leaning out, running out of fuel. That can be the strainer at the gas tank, any fuel filters it has. Disconnect the fuel line from the carb and see how good the flow is to it, and check for water. A new spark plug never hurts.

My toro 6.5 hp push mower (2010), has no fire to the plug. I have not abused it. i have a small yard and it just gets normal use. Now it won’t fire. I first changed the fuel and cleaned the carb thinking it was that crappy ethanol again. but i grounded out the spark plug and cranked it…no spark. I think it has to do with the lever you pull back to start it . they have some stupid complicated safety contraption that rides along the fly wheel when you pull back on the handle for starting and shutting off the engine. …it looks worn out already…like a mini brake pad. any ideas?…do i really have to replace this garbage every year or am i on the wrong path here?
ANSWER : Unhook your wire from the coil that goes to shut off mechanism, and see if you have spark then. the wire may be grounded out, or your coil might have took a ****

Mower starts and immediately shuts off and wont start again if i let it sit for five minutes it does the same thing checked oil and air filter carb is clean attempting to find correct socket to remove plug
ANSWER : Pull the fuel line from the carb & see if it is running steady, If so the next check is the carb bowl to see if maybe the float needle is partly plugged, and then it could be the valve lash clearance which will require more mechanical knowledge.
