Try cleaning or changing the air filter...........also check for blockage in fuel line or change the fuel filter if it has one.
won't stay running starts and goes then stalls Sounds like might be a float ,fuel filter or maybe just needs a good cleaning. Hope this helps.
Possible buildup in the line from the gas tank to the carb.
dirty carb bowl or water in the carb
There are a couple of reasons why a lawnmower will not stay running or not getting fuel. The carburetor may be clogged up or the lawnmower gas may have water in it.
remove the the bowl on the carb and clean with carb cleaner, be sure to clean the main jet. and the small holes in the bolt that holds the bowl on, if these are plugged the mower will start but not stay running
clean the air filter air is being restricted
You might have a sticking float. Might also check the fuel filter - it might be clogged.
The fuel filter is clogged or the carburetor needs to be cleaned and/or adjusted.
Find the sensor which is located under the seat, there will be two wires connected to it. Cut them off the sensor and join them together. The sensor is there for your safety, if u fall off the mower will stop running Most tractors will stay running if you put every thing out of gear.
Check float , fuel cap, fuel filter, Probibly a good carb cleaning would do the trick. Hope this helped
