@ladydi4357 ,Diane, Before you go removing the or changing the filter if applicable, Remove the gas cap and see if it runs(do not run too long because of splashing fuel). If mower seems to run good with out cap, this means the vent hole in cap is plugged not allowing/restricting fuel to flow. Replace cap or try to clean vent holes. Other things to try install new spark plug, check for pinched fuel line, remove fuel line to see if you have fuel flow from tank, if equipped with fuel pump remove fuel line from outlet on pump turn/crank mower over to see if pump is pumping fuel, remove carburetor and clean thoroughly/rebuild set float level. Good luck.

I hope this helped you out, if so let me know by pressing the helpful button.

It sounds like the carburetor may need servicing. Typically caused by using old gas or leaving gas in the tank for an extended period of time. What happens is that the volatile components of gasoline will evaporate and leave behind a sticky varnish like substance that clogs up the carburetor. Its recommended that you use an additive like Sta-bil or Sea Foam to a fresh can of gas. I personally use 1 oz. of Sea Foam for every 1 gallon of gas.
