Vandyke 'Regulator'

I am trying to get an old family "Vandyke Regulator" working . It was 'repaired' some years ago but I have never been able to get it to run for more than a few minutes at a time. The mechanism has been recently completely dismantled, cleaned and (lightly) oiled, but it still will only run for a very short period of time. I believe the problem lies with the ribbon escapement - but I may be completely wrong.

I have attached a video of the movement, and would be most grateful for any advice as to :-

a) where the problem lies
b) how to go about rectifying the problem

Thank you for any help you are able to offer.

The recoil is good. If you take off the verge and then stop and start the escape wheel with your thumb, does it snap quickly to life or does it appear a little sluggish? I do see some badly bent teeth on the escape wheel. Those should be pulled to a nice point again. Shark teeth like those will kill the escapement action.

Thank you shutterbug for responding to my post.

The escape wheel when freed very radidly spins up and runs completely freely.

I'm completely new to clock repair (as you might have guessed !). Could you suggest how I might pull the escape wheel teeth to a point.

Thanks again

Get some smooth jawed pliers (small ones). Then line up on the flat part of the teeth and apply a little pressure and pull straight off the point. That should straighten things out.

hard to see, but the suspension spring looks like it may be twisted/kinked a bit?

also, make sure the crutch slot is not too tight... that can add unwanted friction.
