Sounds like retarded timing. Advance it a bunch while idling and see if that helps. If you were 180 out it wouldn't run at all.

Look down the carb throat and verify that your accelerator pump is giving a good shot of fuel into the venturi.

Check for vacuum leaks by spraying starting fluid onto all junctions - carb gasket, intake gasket, vacuum hoses, etc.
