A full gas tank and oil reservoir are the essential first steps when checking why the lawn mower won`t stay running, but the problem could also be a dirty filter, clogged carburetor, improper fuel mixture, or a dirty spark plug.
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.
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.
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.
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.
Another reason a mower might start and then stop is that the air filter becomes blocked. If this is the problem, then it`s good news because it`s easy to fix since most mower filters are cleanable. Check to see if the filter is blocked and clean as necessary – then try again to see if this has solved the problem.
You Lose Power in the Middle of Mowing:
Here`s why this happens and what you can do: Dirty Air Filter on Your Lawn Mower: Clean or replace. Dirty Spark Plug: Clean or replace. Build Up of Clippings & Debris: Clean underside of your lawn mower deck as noted above.
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.

I have a husqvarna 323L string trimmer. I stored it after running the tank & carb dry for about two years. I fueled it, then started it, & it ran for a minute then died like I turned the switch off. Since it would not restart, I found the fuel filter had broken off the hardened fuel line & it sucked gummy crap out of the tank & into the carb. Failing at cleaning the carb, I finally put a new carb on it & replaced the pump, hoses & filter. It has ran good till this year. I winterized it with stabilizer & left it with a full tank over the winter. The gas in the tank was gone when I got ready to use it this year. I filled the tank with premix, checked for leaks, then started it. It would run fine for about half a tank, start idling poorly (lean) then cutoff & refuse to restart till I refilled the tank. I finally found the tank had cracks & was letting pressure out of the tank & apparently this was causing the carb to lose it’s ability to siphon gas out of the tank. So I replaced the tank which came with new hoses & a filter, which I properly installed to the carb. It cranked right up, but when it runs a half tank, the carb quits sucking gas out of the tank. When I pump to prime the carb, it moves the fuel into the carb, but the pump never gets hard like it does when I prime the carb when the motor is cold. I have to keep refilling the tank, prime, & then it starts & runs until the tank gets about half empty. The new fuel filter is down in the gas tank properly, but It will not run after it shuts off until I refill the tank & prime. I’m baffled. New tank, new hoses, new filter, new carb, & I can find no leaks in the fuel system. It runs strong. The 323L is a two-stroke & it always cranks on the second pull from cold on a full tank. Any ideas?
Where is the primer ball
ANSWER : It may not have a primer ball. If it does, it would be attached to the carberator. If it starts, but won’t stay running, that could mean your carberator needs to be cleaned/serviced.
Lawn mower will start and run for 5 seconds and shut down
ANSWER : Will it stay running with your choke on? if so then clean your carb. if not then look for a blockage from tank to carb. ie fuel shut off, deteriorated fuel line. plugged filter etc
My mower will start but won't stay running – Toro LX466 22HP Lawn Tractor 13RT61RH244
ANSWER : I am going to respond 2 times to this post. The first reply will be generic things to check.
First off check the oil level and make sure it is serviced to full.
If your having a lack of fuel (runing lean) you will need to check fuel flow at the carb fuel mainfold. It should fill a spray paint can lid in less than 10 seconds but teting flow rated of the main fuel line. If you have poor flow here… you need to check the fuel filter and the fuel tank outlet port for obstructions.
Good Fuel flow still shutting off…. remove the carb float bow and clean the debris from the bow’ and the treaded area where the fuel solenoid mounts Additionally you will have to again remove the main fuel line and spray carb cleaner in the float needle area to flush out any debris through the fuel hose connection.
For the second response I need to know which engine is installed on your mower by MODEL number if you can locate it. (there are 3 engines) At least try to find the engine model number. If you can not locate it Brand and HP of the engine (I assume 22 hp) Thanks for choosing FixYa,
