I got my clock to run sometimes hours , sometimes minutes. It's an old English movement and I was always noticing how short the swing is. From 0-30 seconds, the beat is very smooth but 30-60 the beat is inconsistant. I am thinking that the escape wheel is worm and should be replaced?

What I think you may have is a bent pivot on the escapement wheel arbour, which will lead to inconsistent beat through the 60 beats per min cycle.
