I have an "Eureka Clock" that is running slow, about 10 seconds per minute. The advance pawl is advancing properly ( 1 tooth/revolution). The poising weights are screwed all the way in (none are missing). The balance spring appears to have the correct no. of turns (approx. 12 1/2) and is in the clamp as far as it will go without protruding from the end. Shortening the spring does not have effect of the timekeeping. The balance wheel rotates about 355 degrees , using a 1 1/2 volt "D" cell. All the wheels in the movement move freely.
Has anyone else encountered a similar problem, and if so how was it resolved? Or, does anyone have any thoughts on how to resolve the problem?
