I Have a Briggs & Stratton 14.5 OHV on my riding mower. I was mowing my lawn and my mower started to die. I moved the throttle around and it kept running. A few minutes later it dies. I look over everything and it looked normal. I tried to start it again and it fired back up. 30 seconds later it dies again, but this time it will not restart. I let the mover sit for about 30 minutes and try to restart it. It fired up and ran for about 5 minutes then dies again. I poured fuel down the carb and it fires back up until the gas is gone. I checked the fuel line & fuel filter. Both were good. I took the carb apart, and all the jets were clear. I even changed the fuel, and changed the plug. If I leave it sit for a while it will run for about 5 minutes then die. It will start on the lowest throttle setting briefly, then die. Can anyone give me any suggestion on how to fix it? Thanks in advance.
