Just flushed my carb and fixed a fuel line. Ran fine when I first fired it up. I ran around the yard for about 15 minutes and all of a sudden it started to back fire then died. I got it restarted and rode around back and it got much worse. Now I can barley get it started and is back fires bad through both the Carb and Exhaust and will only run with the choke on if at all. Please some one have an answer for me.
