@komet163b / Wayne -

Here are some more photos and I am adding photos of the check ball's size on from my digital calipers (never know when someone is trying to replace their check ball).

The first photo is where I put in a tooth pick - this is so you can see how far up the shaft goes until it hits the top of the hole for the ball.  You can see that I have the o-ring still on and that would be the stopping point for the shaft to the top of the pipe.

The next photo is to show, if you look real close, the shaft coming down halfway through the hole.  I can't spy anything on the bottom of this shaft that could bind, so I am thinking the problem is further up on yours.  But I am just guessing.  Not sure if these photos will help you but they can't hurt either ;-)

Last photos is just the size of the ball, in MM, Inch, Faction.
