When was the last time you had the carbs synchronized? If they are not flowing the same it could couse this problem.

You should check the valve clearances, camshafts timing and make a compression test on the engine too.
One or more of your inlet valves is/are either not closing entirely or they close but their stem is damage and it doesn't seal off the combustion chamber properly.
