Hi all !

I'm looking for the size of rubbers to put on the posts below the two ramp ends on my Flinstones.

The machine came without any rubbers on these posts and when the ball gets out of the left ramp (mutliball is a good example), it tends to bounce on the slingshot rubber and go directly to the outer lane ! Bad game experience !

I think posts are 02-4434 reference but didn't find any info in the manual, either on the post or the related rubbers.
I'm hesitating between 3/8 OD and 7/16 OD rubbers, but i might as well be someting else. I don't have much experience in this.

Here are two photos of the posts.

Additionnal question : these posts are fixed in slots, not in simple holes.
I suppose it's for adjustment but what is the purpose ?
Making the game easier or harder by changing the outer lane access, or catching and bouncing the ball correctly in the inner lane when it gets out of the ramp ? Maybe both ?

Anyone with an idea ?

Too specific question ?

Thanks for the input !
I think i'm going to order both sizes and I'll tell you what works best for me, including post positioning.

Coming back with some news, after quite some time...

I just installed 7/16 OD rubbers on the posts and it fits well, no ball hang up with these.

It improves the outlane bounce problem when the ball comes out of the ramp, but does not totally eliminates it.

After some thinking i understood what is the cause : it's the diverter assemblies.
They have some lateral movement so when the ball hits the diverter metal plate, it produces a bounce effect while the ball falls from the ramp. This effect is amplified by the slingshot rubber.

Holding the diverter whith the finger eliminates the bounce effect and the ball always neatly takes the inlane without bouncing.

I don't have a fix yet, i don't know if the diverter lateral movement on its axis can be reduced.
Maybe it's due to wear on the coils tubing... ?
