My riding lawn mower starts up fine but stops running after 1 min

check your vent hole on fuel cap,or just loosing the gas cap so it can get air if this helps than you know it is the vent.

Did you take off the fulter and look at it or the gas cap

Had the same thing, clean the hole on the gas cap.

It's one of two things. My first thought is that you have a clogged gas cap. Try loosening it when the mower starts to run ruff. If it smooths out again and runs fine, then you know that the carburetor is not venting properly. Either buy a new gas cap or clear the breathing holes in the cap, if possible.

The only other thing it can be is that your Ignition Coil is going bad. A bad Coil, once it gets hot, will shut down. But it usually takes longer than 5 minutes for them to cool down well enough to start back up.

My Vote is the cap!

Good Luck!

Try this:
As soon as the motor begins to stall, loosen the gas cap. If that helps, clear the vent holes on the cap.

Try this.
When the mower is about to die, loosen the gas cap.
My mower gas cap vent holes plugged up and kept stalling the mower.
If it works, drill out the vent holes.

Try loosening the gas cap a little...... there is a normally a small breather hole in the top or underside just above the seal which allows a small amount of air to enter into the fuel tank. Sometimes this breather hole gets clogged..... stopping air from entering into the fuel tank as fuel is used. Eventualy enough vacume pressure accumulates inside he tank causing a vapor lock. If you loosen your fuel cap slightly.... this should prevent the problem your experiencing. If it does... try soaking cap in deisel fuel or heating oil overnight, remove and allow to dry prior to re-installing. If the problem persists after a good soak, only option is to replace fuel cap. GOOD LUCK!

Simple thing is to check the filters..air & fuel. Good chances is if it is not in the carburetor then its the coil. www.nnyparts.com

From the rear of machine look at the top left of fuel tank for the fuel line.Where line comes out of tank see if it is pinched where it goes down between frame and tank,grab line and see if it moves freely.If that is OK loosen fuel cap after 10 minutes of run time to see if your vent hole in cap is working.These are 2 common problems for the L series mowers.

try spaying carb clean or starting fluid in carb & try starting it if that doesn't work e-mail me at [email protected] thanks,wade
