Hello I'm new here and I'm also new to working on clocks. I recently inherited a grandfather clock from a family member. The clock would not run at all when I got it. I watched some YouTube videos and made some minor adjustments and I have it where it is working and chimes but the chime one minute behind. My next problem is it chime on the hour at 15 min skips 30 min then chimes at 45mins. Stamped on the movment is a 81 so I'm guessing that would be the year it was produced? Any help would be greatly appreciated.
