Question
I have cleaned and oiled it. It runs good. However it runs extremely fast. I have adjusted the lever in the back and it helps some but still gains up to an hour a day. The clock is spring wound. The lever controls what I would call a wound hair spring.

Answer
if there is some dirt or oil in the coils of that balance spring or some of the coils are touching, then the clock will run fast.  


After that,the length of the spring in the coil is another adjustment that can be made- the outer end is most often pinned and can be repinned at the end of the spring to give it longer  length --but then the center shaft collet holding the inner end needs to be repositioned to get the springs occilation to balance again-----all this is very delicate work for an experienced repair person if the cleaning mentioned first does not solve it

His responses were clear, addressed my questions and concerns in a way that even I could understand, and even sent a picture. He explained what I had and how to resolve the issue. I was amazed at how quickly he replied to each on my e mails. He shouldn't get a gold star, he should get a whole box of them!!! Thank you Mr. Saunders, I will keep you on my e-mail "speed dial". Comment - Ken answered my question regarding how to adjust the proper striking of the hammers on my Grandfather clock within a few minutes of my sending the question to him. He answered my follow-up question the next morning. I would rate him higher if there was a number larger than ten in the selection box. Thanks again Ken Comment - I RECEIVED AN ANSWER WITHIN AN HOUR.OUTSTANDING SERVICE.YOUR RATING SHOULD BE HIGHER THAN 10.

Comment - It's happening!! The clock has run for about 8 hours...I appreciate your quick response and clarity of directions. Thanks so much ! Kenneth really knows his stuff, he has the knowledge about where you can buy replacement parts and where to get repair service or do it yourself. I think I can fix it myself and receive the full value of my clock. He even sent me pictures of clocks like mine sold online so I could get a good idea of the value. Thank you Kenneth for responding so fast and making me feel so confident in repairing my own clock. I vote Kenneth Volunteer of the Year.
