Check the gas tank cap, there should be a small hole to let air in as the fuel is used. If it's blocked air cant get in and as fuel is used a partial vacuum forms in the tank, the fuel stops running and the motor dies.

Sounds like you checked everything but the gas can.

    Check the gas tank cap, should have a smal hole to let air in. If it's blocked air cant enter the tank to replace fuel as its used and you get a partial vacuum in the tank and the fuel stops flowing.

Mower starts easily, but runs 10 seconds and quits.

Carburetor needs to be cleaned; main jet is clogged with debris, dirt, whatever.

Jun 23, 2015 | Garden



This is a basic lawn mower problem that haunts all the little gas engines in all makes and models of lawn mowing equipment....stalling and hard starting due to fuel problems stem most of the time from dirty, varnished fuel that has been left sitting inside your mowers fuel tank, fuel lines and carburator.
Also be certain the air filter gets replaced quite often they get dirty and clogged rather quickly, but back to your fuel system problems....lets address this in stages...first step is to drain and flush the fuel tank, the fuel lines, and the carburator(remove the carb. bowl).
Next step with a can of carb cleaner and a pair of eye protectors spray out the carb real good hitting all the small orifices(hol;es machined into the carb. body to transfer fuel or air) they have a habit of clogging up, also the small brass center fuel bowl you removed to drop the fuel bowl down for cleaning has a hole and a small vent valve in it do the same for it, next remove the carb. making a note of how the small linkage springs and rods go to meke installation easier when iot comes time to put it all back together, with the carb off, soak it in a mild degrease solution over nite, next day, gently blow out all the solvent from the carb being careful not to lose the needle and seat valve that controls the fuel/ float flow, when all finished reinstall the unit being sure the bowl fuel ring gasket is installed properly as not to cause a fuel leak, check after you get it running and all new fresh fuel is added , to see if the carb adjuster screw needs to be adjusted, it is facing the outside of the mower toward you and on the side of the carb around where the linkage is pivoting from.
90% of all problems with these small engine stalling and starting is due to these very basic repairs, if you do it yourself you will save $$$$ everytime.
Happy Mowing!!!!

There could be some type of contaminate in your fuel/lines. Check for that!
Then check your fuel filter. and hoses.

Your carb needs to be rebuilt!

See below

A couple things, is it full of grass and hay up top that would cause it to overheat? Or the fuel filter got clogged up from debris in the tank. Or the governor spring came off, loose, make sure it moves freely, and then check the air filter. Then before filling the tank up, peek in there with a flash lite and see if there is any water floating in the bottom. Then check the spark plug. Hope one of these helps.

I would take the bowl off the bottom of the carb.. Probably you have clogged up holes that let the gas into the bowl.Or either the needle is stuck up not allowing the gas to flow...That's why pouring gas in carbs would let it run for s few seconds....Also try fresh gas..Gas doesn't have led in it anymore..It don't last year from year...After grass season is over..Buy some from Lowe's or home depot..Pour it into your tank and let the motor run to get it done into the carburetor...Then the next year it will start

it sounds like you may have a vapor lock on your fuel tank   there should be a diaphragm on the inside of the fuel cap  that lets air in but not out   it may have an air hole clogged  take the cap apart if you can and clean it real good and put it back together   if that is not it  then the float in your tank may be stuck   or a fuel line filter may be clogged

Toro Lawn Mower Won't Start

this is a very common problem with these toro mowers. the needle valve in the bowl of the carb. is plugged up with dirt or varnish from the fuel. just under the primer bulb there is the carb bowl. it has a nut under it that holds it on remove the bowl and make sure fuel flows constantly while the bowl is off. push up on the float to stop the gas flow. this could be messy and dangerous. careful with the gas. its flammable. best solution is to remove the carb and soak it overnight in a parts cleaner like gunk. caution small parts inside. this happins every year on mine no matter what i do. seems like the orifice is so small it clogs easily. good luck
