Assuming it was working ok previously then one of the simplest issues, especially if the clock stopped working after being moved, is that the floor it's standing in isn't at the same level as where it was before, so if your floor is dead level, and where it was before was slightly off or vice versa this will put it out of beat. This is particularly true of long case clocks, owing to their height. Being a mm or two off can easily stop them. You also need to ensure that it is standing up straight, and not leaning forward or back. You can check this by taking the hood off and looking at the top of the pendulum. You will see that it passes through a slot in another rod, this is called the crutch. It should be reasonably central in the slot, certainly not touching at front or back. If it is only slightly off then this can be corrected by simply inserting something under the front or back of the case as appropriate. Veneer edge banding is good. Symptoms of being out of beat are that it will run for maybe a minute or two and then stop. You will also probably notice that the beats sound different, usually louder on one side than the other. Easy to check. Attach a piece of paper to the inside of the case back behind the pendulum with blu tac or similar, as low as you conveniently can. Stop the pendulum and let it settle. Now mark that position on the paper. Now move it slowly to one side until the clock tics, and mark that position on the paper. Move it slowly the other way and repeat. If the clock is in beat then the marks to either side should be equidistant from the centre. If not then the easiest way to correct it is to insert something under the feet or plinth on the side with the longer distance to lift it slightly on that side until you can repeat the measurements and get them the same. This will be fine if it's not far out. If it is a long way out then the movement itself will need adjustment, or there could be something more seriously wrong. I wouldn't advise doing any adjustments to the movement yourself unless you know what you are doing, you could potentially do a lot of damage. As a guide I would say if you need more than maybe three strips of veneer to correct it, then time to get someone in to adjust it. Unless of course your floors are a long way off being level, in which case you may need to make up a board for it to stand on to compensate. Had to do this at my dad's cottage, don't think there was a right angle or level surface in the whole place!
