suzuki rm 80 wont idle?

[kennethg772]

suzuki rm 80 carb is out of adjustment, and ive never messed with bike before. Theres 2 adjustable screws on the card but which is which?

bike runs good, but wont idle, just stalls. ive tried turning both, but not sure which is which?
thanks for the help

One should be an air screw (near the rear in most cases) and a bigger screw for idle (usually in the middle, and bigger than the air screw)

ok what you do is find the idle screw and turn it all the way in and then you turn it out a turn and a half and go from there turn it out just a little but at a time to get the perfect idle rpm
