B & S 12.5hp rough running then stopped

Hi All,

First Post from me!

I have a Husqvarna LT25 ride on with a 12.5hp B&S engine. Its quite old I've had it 4 years from eBay. Recently its starting running a bit rough, hunting a bit etc.

Ive changed the oil, air filter and stripped the carb down and cleaned it out.

Now it starts and runs fine for about 15 mins then just slowly runs down and stops. Im guessing it must be the fuel/air mixture as the engine warms up. Ive tried adjusting the little screw on the side of the carb but this doesn't make much difference.

Any suggestions?

Thanks

Can you post up the engine number (type)

Sounds to me like you have a fuel blockage. Check the fuel cap. Loosen it and see if it still happens. Look inside the fuel tank and see if dirt or foreign object is in there. Blow out your fuel lines back towards tank never towards carb the retest. Let us know what you find.
