Toyota 850AD

Need help!
I have a Toyota 850AD, I have timed it by the book the needle bar is timed by the timing lines, Have timed the hook, but it still won't sew. When I position hook the 1mm from needle it pops the needle thread every time, if I back it off it doesn't pick up bobbin. Everything I have timed before when it picks up bobbin and is not hitting needle would sew. I cannot get this one to sew.Any help would be greatly appreciated.
