I have replaced the coil, fuel filter,air filters and seat switch. the mower will run 10 to 20 minutes than stall out.i come to find out when the mower sets for a while the fuel filter will fill up about 75%,and when you start the mower you can watch the fuel filter and it will stay the same for about 13 minutes than you can see the fuel in the fuel filter getting lower than it stalls when the gas runs out of the filter.you leave the mower set and it will slowly fill up .i changed the gas cap with a new one. i also blew out the fuel lines.this mower is only 5 years old. help clarence

Clarence,

Get a mason jar, disconnect the fuel line, place it in the mason jar and see how many seconds it takes to get a cup of gas.

Run the mower until it stalls and repeat the test, you should get the same quantity. If you do then we need to look elsewhere for a problem.

I am assuming the oil level is good and has been changed on a recommended basis. Make sure it is not contaminate with fuel, if you pull the dip stick out and smell it, it should not smell gassy.



Also, after it stops, have you checked to see if the tractor has spark?



Let me know.

That's good to know, it looks like it is not a fuel supply issue. The carburetor has 2 fuel feed circuits, 1 is or idle / off idle and the 2nd is for high speed. I would turn the fuel off and remove the fuel bowl at the bottom of the carburetor. Does your carburetor have a fuel shut off solenoid on the bottom of the bowl? If it does you would unscrew the solenoid, that is what holds the fuel bowl in place. Check for rust, dirt or debris and clean. Do not remove the float or needle. Reinstall the fuel bowl, don't over tighten the bolt/nut/solenoid, it just needs to be snug enough not to leak.

If there is no debris, leave the solenoid wire disconnected and see if it stalls. Check the spark too, I didn't want to forget that.

Good luck.

Regards,



Have you ever heard of "sea foam", it's a fuel system cleaner that will remove fuel varnish from the inside carburetor channels, you might want to use some as a maintenance item.
