Incredibly Fast Rev After Routine Maintenance

Looks like mine is missing a spring on the fast idle lever.

Yeah, throttle return spring missing? When you let up on the gas pedal, the spring returns the throttle plate to the idle position. Is there any resistance when you step on the gas? That would explain the high engine speed when you started it up again.

And you ARE missing the fast idle adjustment screw as you thought.

If nothing else, you can go to your local hardware store and rummage through their spring selection to get you back on the road. Measure the length you need to go from point A to B and pick one a little shorter. Or adjust the length with wire cutters and needle nose pliers.

Since you are in Florida you can wire the choke open temporarily to keep it from getting in the way of normal operation until you fix it.

If you have not moved the car recently, the parts may be on the ground under the car.
But the best thing to do is get the correct parts. Can anyone on here help him out?
