HI,

My craftsman LTX1000 lawn tractor with a B&S 21.5 HP engine will not stay running. I have changed the fuel pump fuel lines and fuel filter and get the same result. It will start and it acts like it is running out of gas. If I pull the choke it will run a little longer then die. I have pulled the bowl off the carburetor after it dies and there is fuel in it. I don't know what to try any more. Has any body else had this problem if so what is the fix.

Thanks

Chris

Did you clean the fuel tank when you were working on the unit? You may have to remove the carb and do a thourough cleaning.

I have the same mower, and had what might be the same problem. It turned out to be a sheared flywheel key. Apparently the spousal unit hit something pretty solid and "forgot" to tell me about it.
