I have a fusee wall mounted clock with pendulum.
When I adjust the clock body on the wall to get an even beat the 12 o'clock/6 o'clock positions are not quite vertical - at least I can see it and I'm a fussy blighter.

Is there any way if correcting this?

You have to adjust the crutch to level your clock. The crutch is the piece that pushes your pendulum side to side. If it is flat you just have to push it to the side that you are getting the short beat on. If it is a round wire you have to bend it toward the short beat.
