Door Stuck On Opening

I think the face of the strike (where you put the star bit) is rubbing on the inside of the latch. Try taking the extra washer out and see if that helps. I think Dana67Dart is on target - the door has to close with no interference without the latch in the mix.

I put the washer behind the door strike because, without it, the latch was hitting the "collar" of the strike post. Not the smooth post part.

If I take the strike post out, the door closes to the body with no interference. I think that is what you are talking about.
