Hi, Anonymous and the usual suspects are:
1. Throttle cables improperly adjusted, pinched or need lubrication.
2. Idle adjusting screw needs to be backed off.
4. Air fuel mixture adjusted too lean start with 2 full turns.
5. Intake system air leak.
6. Fast idle choke ramp is not releasing.
7. Broken throttle return spring.
8. Damaged diaphragm or slide.
9. Faulty MAP, TPS, ATS, O2, sensors or wiring/connector

take some wd 40 & spray around the carb boot while running to see if the idle drops for a few seconds. sounds like you have an intake side air leak causing a lean condition making the motor rev high.

Reving High


Did youmtry disconnecting the battery for five minutes, then reconnect, start engine and let it idle for 5 minutes with everything off, including radio and heater. If this don,t work you may have a faulty position sensor. I hope this helps.
