Are you adjusting with a vacuum gauge on it and have you adjusted your mixture, too? Has the carb been rebuilt in the resent past? Could be the mixture, a carb in need of a cleaning or rebuild, or combination of some or none of the above.
If you're not adjusting with a vacuum, I would start there. Check timing and all the stuff that goes with points, too, if you don't have a HEI distributor.
