Working on restoring a 1980 Black Knight back to health and I'm almost there. I've noticed that the ball jumps quite a bit when I shoot the middle ramp and miss, and the ball hits the rubbers flanking the ramp. I'm using small white rubber rings, but I'm wondering if I should be using some other type -- perhaps those cylindrical ones. Can anyone comment on this or share their experience. I'm fairly certain it's being caused by the rubbers.
Thanks much.
