Tractor runs rough

I have a Sears 12 hp riding mower with a Tecumseh engine.It runs fine under load but as soon as I disengage the blades and reduce the speed it runs rough and backfires.I have tried adjusting the low speed screw on the carburetor, but it makes no difference.Any suggestions?

The high speed screw is probably the adjustment that would make the most difference here. If adjusting it doesn't help, you may have to clean the carburetor.
