Idle too fast. was created by Stevetaylor
1971 merc 250ce. Finally got the car running reasonably smoothly. Issue is idle sitting at 1500 recs even when warm. Have moved throttle switch back until it starts hunting but doesn't slow down, air idle screw has little effect. Is there a base setting for the throttle plate, as in an air gap between plate and body.

Should throttle plate be totally closed on idle or should there be a slight gap between plate and housing.?
