sounds like a vacuum leak. My car did the same thing, mine was leaking between the carb and intake, had the wrong gasket .

Try a compression test - betetr yet a real leakdown test with carb open- se if ther may be a exhaust valve not seating correctly-Thats my guess? should show low or no compression on 1 at least?/
