Hey guys, I have the same problem as Frankly Frank. Only my mower will start some times and run for a while and then just quit. When it runs it runs well and then just quits, like some one turned off the fuel. After that it will just crank and crank. It will try and run but only sputters and backfires. I have cleaned the carb and drained the tank as well. I have a new fuel filter, solenoid, changed the oil, and spark plug. Can any one help?
