Stalling Problem - 88 accord

I have an 88 accord dx, carburated. Recently it started stalling all the time. At start up the car idles high but as soon as the choke opens it start to stall every time I push in the clutch. It has been wet lately and I though it was jsut condensation in the distributer but it hasn't gotten better. Any ideas? Could it be a sensor or relay. Id rather not jsut turn the idle up, becasue nothing changed with the car, it jsut started happening one day. Please help me. Thanks
