Could be a number of things. We do not know the condition of the engine. Hard to diagnose engine troubles over the internet.
Based on the limited information provided, a couple of things I would start off checking, Is the vacuum advance on the distributor functioning? Set initial timing to 12º BTDC with engine at low idle and vacuum advance disconnected.
