Casey, Have you tried turning the idle screw on the carburator? Should be a small screw located at the bottom of where the linkage from your gas pedal attaches to your carb. The screw should have a small spring around it & should be turned in a clockwise direction until you get the desired idle. I suggest that you purchase a Haynes or similar book for your year Elky. They can guide you through basic tuning. Jon

Although this could be a vaccuum leak or a mis-adjusted carb, it could also be something else. Does the car hesitate on hard acceleration? Turn the idle screw a bit to see if that helps and/or check carb for vaccuum leaks, also vaccuum lines (cracks or not on properly). Was the carb rebuilt? Is it a new carb? Other things that could cause this, timing, plugs, plug wires, distributor cap, rotor, coil, fuel pump. Start with the easy/cheap stuff and work from there.
