I always run on "super" petrol in the old cars now, the "regular" stuff just seems to go off after about two weeks and is useless and would run the way you describe.
Had similar on a different car this year. (HIF44 carb on A Series engine).
It had a blocked breather pipe that made a big difference as it ran perfectly at low revs but wouldn't do anything else.
Changing the dashpot oil to correct spec fixed the issue completely.
