What can I do to fix the ball from stopping here? If the ball has enough speed, it will go through, but the clearance seems tight. I tried to adjust the metal pin (I don't know what else to call it) but there is no give. On a slow draining ball, it will just stop and I have to bump the pin for it to fall.
Thank you for your help.
