Okay, recently I began my first major automotive project, a prelude which hadn't been run in twelve or so years. So, I took apart the carbuerators, cleaned them and rebuilt them. However, the car now only starts when someone jams the choke plates tight against the barrel walls. Also, fuel sprays out of lines where there should be vacum. If I release the choke plates, the motor revs to about 3000 and then dies. I am certian, that sumthing is falsely connected in the vacum system, but I don't know where. Could somebody help me?
