engine trouble

did you put new gas in it when you drove it last?it sounds like a fuel problem.if you did not put new gas in the old gas has broken down and has water in it or the gas has dried up inside the fuel bowls or the fuel filter just gave up and is clogged up

the fuel filter is clean, how do i adjust the float on a demon 625 carb? the big problem is that is stalls out under any kind of throttle push
