    I had a case with the pendulum bob and hands, so I ordered a referbushed movement but it seems to be a little fast. I adjusted it as low as I could before it touched the bottom and it's close but it's still fast. Is there anything I could do or should I leave as is? I probably bought a similar movement that was slightly larger then what it had originally

    You already have a clock case married to a non-original movement so I assume this clock has no huge value. Perhaps the simplest thing to do is to cut out the bottom of the clock case under the pendulum to clear the pendulum and adjust it lower. Some clocks have such cutouts originally. A thinner suspension may help as well. Is the clock otherwise running strong with a good pendulum swing? One cannot regulate a clock that's not running properly.

    it is running well. The movement was restored and had been tested on a stand before I got it. As of now I adjusted the pendulum up a little and over 10 hours it's maintained the time. I'll see if it holds after a day or so

    Could you use a smaller pendulum bob?
    Perhaps lower the center of the mass...

    I would try Buju's suggestion first.

    Also, shortening the suspension spring 1/4" will raise the pendulum's effective length about 1/8". So, if your suspension spring looks a little long you can try this trick.

    As of now it's no longer fast but a little slow, so I don't think I'll have to change anything on it other than increasing the pendulum height to fine tune it. I'll try to see if I can get some pictures up.thanks for the suggestions

    It was an listing I ran across on eBay, I can't find the sellers info anymore, but he serviced the movement and tested it on a stand listing the pendulum weight used to test. He also adjusted it to to get it on time on the stand.

    There are several people, many of them being members here, who refurbish and sell old movements. However there are other people who claim to do so, but wouldn't know a refurbished clock from a piece of junk. You have to ask specific questions to sort them out (they won't have or even know the specific answers).

    Good to know, I went with this guy as he had some details on it rather than just saying it runs.

    And then there's the traditional assurance from the local antique dealer: "It runs, but the key is missing."
