Did you by chance change one of the screws holding the points or condenser? If so it may be hitting the counterweights, springs or other items below the point plate. It’s a easy thing to remove two screws that hold the plate in place and have a look.
Please keep in mind it’s been a while since I’ve looked below the points if my info is a bit off. I do know it’s not a challenging job.
