if that part you mentioned trips (the ring wobbles about) but the sear doesnt trip then you might have the same problem i had with mine, the capacitor wire had broken meaning it didnt have enough charge to trip the sear.
Here is the link to the problem including my solutions on there on the kingman boards ...
