New clutch setup won't disengage

I doubt the disc is stuck to both the pressure plate and the flywheel, which s what would have to happen to get what you say is going on.

With that said, when a car won't go into gear while it's running but will with the engine off, it's from a lack of air gap. The clutch is dragging.


So, get more air gap. Which is easier said than done with your bell housing.

Any reason why you went with a hydraulic clutch? I been around them and I prefer mechanical linkage if I can get it in the car.
