Hello John
I ran into the exact same problem a couple of weeks ago so maybe I can help.
If it's all setup correctly then it might be one of two things. The first one which seems too simple but was a problem that I had with a prior American time only clock was that I had the minute hand on upside down! Really, it was that simple but took me forever to figure it out.
The second clock was a newer mantle clock. Turned out that the hand had slipped a little on the square collet it is mounted on. I just put a square jewelers file in the square hole and turned the hand backward a little and that took care of the problem! Seems they are frictioned on and actually adjustable. At least this one seemed that way. Have a little background in watches but fairly new at clocks so don't know if they are meant to be adjusted this way but worked for me with no damage to the hand.
Good luck and hope it helps, George Howard ( a lot less bored now!)
