Your lawn mower turning over but not starting due to several reasons, such as a faulty or disconnected plug, a disconnected spark plug wire, a clogged air filter, or a contaminated fuel tank. A faulty carburetor, a dirty cutting deck, or a dysfunctional flywheel brake can also cause this.
If the plug is clean or you`ve replaced it and the mower still won`t start, the issue could be a lack of fuel. Either the carburetor is dirty and not able to mist the fuel to be mixed with incoming air, or no gas is getting to it to begin with.
An airlock is one of the common causes why your mower won`t start after running out of fuel. An Airlock occurs when air replaces fuel in the fuel lines. As you refill your fuel tank, you could push the air towards your mower`s carburetor, which keeps the new fuel from reaching the engine.
If it won`t start or fire with spray fuel, you probably have an ignition system problem, most likely a bad ignition coil. However, if it starts and dies, that proves the ignition is working and the problem is fuel starvation. Check the fuel filter first by disconnecting the fuel line from the filter to the carb.
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.

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.

Check the Fuel Filter

To start, tap the side of the carburetor to help the flow of gas. If that doesn`t work, you might have a clogged filter. Not all lawn mowers have a fuel filter, but for the ones that do, it`s usually located in the fuel line or the fuel tank.

The Spark Plugs

The engine`s spark plugs get worn down and damaged over time due to use. A faulty spark plug can cause hard starts, low fuel consumption, and reduced performance. Spark plugs can be one of the first things you check when your tractor performance is off.

I have a Crafstman Riding mower model #917.273643. That ran fine one second, I shut it off for five minutes. When I went to start it back up it wouldn’t start. Cranks fine, checked the wires, fuse, and spark plug. The plug was dirty so I cleaned it. But I am not getting any spark. I bought a new plug still no spark. I also checked the plug on another motor and I had spark so the plug wasn’t bad. Any suggestions on how to troubleshoot this or what may be wrong?
ANSWER : Sounds like your coil went bad

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 ****

550 Had difficulty starting. Once started it ran very sluggish and then stopped. Checked plug, wired brushed it, cleaned filter, still nothing.
