I have been reading around on the board quite a bit and still haven't seen anything that really relates to this question. After I have my 90 SC warmed up it wants to idle up around 1200-1400 rpm on the tach. I have no other problems with the engine running but I definatly think this is a little high. I still need to clean the throttle plate but I wanted to see if anyone thought there might be something else causing this problem. Thanks
