After numerous adjustments and staring blankly under the hood for hours the problem of a high idle never goes away. With webbers on the engine the car runs like a champ. Only issue is after it warms up it wants to stay at 20000 rpm when standing still (like coming to a stop). I always have to hit the gas pedal (while clutch is in of course) to knock it down to the respectable 10000 rpm. Nothing so far has been a permanent fix and I would like to correct this once and for all. Any suggestions you may have will be welcomed. Thanks, PeterT
