You have to take the generator/dynamo off to do the job properly.
If you are lucky, a previous owner has cut a screwdriver slot in the head of the long bolt nearest the dynamo and the block.
Otherwise, it can be a bit of a pain to get out.
Clean the seating area of the core plug in the block.
If you look at the core plug, it has a sharpish edge where it meets the seating in the block.
So the inner corner of the seating, ideally, needs to be really clean.
So when you hammer the middle of the core plug just hard enough to dent it in, the plug spreads a little, the sharp lower edge digs in, and the seal is made.
Use a bit of sealant if you like.
You will almost certainly have to set the ignition timing again.
