Johnoh, I adjusted my idle by taking up the slack in the throttle cable and adjusting it out one notch where the housing attaches to the throttle body.
Take the clip loose that holds the cable housing in place, and pull the housing out a little, until you get it where you want it. Put the clip back on, and it should idle a bit higher. Just do it a notch at a time, until it's where you want it. You don't want it to idle too high.
