How long has it done it? Have you made any changes before it happened? Did it start all the sudden? Possibly after a fillup? I would start with throwing away the carb and getting a good Holley for it and check your timing.

Check for vacuum leaks. A can of carb cleaner will do the trick. Spray it all around the base of the carb and around where the intake bolts to the heads. If idle changes, then that's where your leak is at.

what size engine, Heads? You should have 30-36 total timing with vacuum at 2500rpm. Might have stuck weights, or just need jetting..
