Hello,
I have a ST double dial with a lyre movement. The clock is running very fast. It is gaining 3 hours in a 24 hour perior. If I lower the bob with the adjusting nut the clock stops running. Could the suspension spring be too long? It does have some wear in the escape wheel but no oblong hole,so I don't think it is excessive. Could the weights be too heavy? I have tried smaller weights and the clock won't run. I have taken the works apart cleaned and oiled. Any suggestions.


Thanks,
Randy

Are you sure the escape wheel is set the proper distance from the verge? Is it skipping over more than one tooth at a time? If so, the verge should be adjusted slightly closser to the escape wheel.

Check your over-swing. That will be a clue for whether you need to adjust the pallets or not. Poor over-swing will stop it for sure.

When you cleaned it, did you dismantle it and check for pivot hole problems?
