    My Howard miller clock has been running for a week and just stopped. I oiled the clock and it still would not start. Please help. Thanks.

    Your post is probably the most common of all post. I would suggest that you search the MB archive and you will learn a lot more about your clock.

    For starters, it's 35 years old and will need to be taken apart and cleaned up, with parts, polished, repaired, replaced, adjusted, etc. Or, it can be replaced.

    Note, the "balance" you refer to rarely gives any trouble. Willie X

    Stopped on it's own, or after you wound it? It should only run a week between winds, so be sure that is not the issue. A little more info would be helpful.

    It was wound and would not start up. I think the pallet is bent. The balance will not move freely.

    Be sure the roller is inside the fork. They can slip out and stop everything.

    Could be a power issue - I had a similar clock with this movement and I found that the balance wheels probably needs plenty of power to drive them! I mainly deal in weight driven units only but when I did re bush the above type movement it fixed the problem. Good luck

    Your clock has a double roller, two small vertical pins at the bottom of the balance wheel. They are double to support the odd looking little safety table attached to the bottom of the double roller pins.

    It's very common for these clocks to have lots of damage from previous attempted repairs. The balance is easily damaged and the first thing they go for!

    The fork position is critical too. But if you didn't bump it, it's probably not the problem.

    I can't really see the critical parts, but that particular balance is often hampered by dirty oil and stuff in the tube. I believe that one has an adjusting tab on it, and yours looks like it's pushed over to one side. That would create an out-of-balance situation and might prevent the clock from starting.
    The rollers sit inside the little fork that turns the escape wheel. See if it is. Also verify that the escape wheel is turning when you move the fork manually back and forth.

    Thanks for the comments, right now that clock is at my other household so I can access it on the weekend. I did try manually working it and it is going in a bouncy motion from right to right.

    If you could make a video and post it to Youtube and link to it here, it would help us a lot.

    I have an article about the floating balance somewhere. If I can find it I'll post it.

    With all the wear it likely has, there is less power at the top of the train to power the escapement. Common for these movements.
