Locate TDC with timing pin as you did, good.
Then use continuity meter or test light to set point opening by loosening and turning rotor. Make sure all shaft back-lash is removed when doing this.
It is important to do these procedures in correct order.

Also make sure the spark advance lever is fully retarded (up) when setting the timing/points.
