Engine troubles! please help!

Idle speed is a fine threaded screw on the carb, that rests against a stepped plate. Screw it in clockwise to raise the rpm.
Mixture screw is also on the carb, but location varies, depending on the carb.
Really, spend 10 bucks on a haines manual for you car, at the least, so you can see the pics, or google the name of you carb and look for images of it on the 'net.

At least by raising the idle speed a bit, you can make it more drivable, although it might not be correct.

good luck
