Stumbling Dellorto's

1980 Darmah. Both carbs rebuilt by previous owner who had throttle stumble and rebuild did not cure this problem. Bike runs great, just stumbles when throttle applied for a second. Does this in all gears, anytime throttle is turned. What could be going wrong? Haven't opened up the carbs yet. Is there an accelerator pump of some sort that is the first to act when throttle opened??
Thanks.
