Quoted from KeeperUSA:

When a city is lit and I hit the left orbit and spinner well, the ball tends to travel straight down the kickback left outlane, rather than hit the post near the left sling. Is this supposed to happen? Anyone else had this issue? What is the best way to adjust it? I have the play field at 6.5 degrees. The ball really flies around the orbit and just shoots down the outlane.
Just stuck a section of felt pad on the metal guide just after the gate near the bumpers, and this has slightly reduced the ball speed through the orbit. The ball now enters the playfield correctly by hitting the left slingshot.
I guess my flipper rebuild increased the ball speed through the orbit, requiring the adjustment, or am I missing something here?

Quoted from chuckwurt:Well they already described one adjustment option. The other is to loosen the ball guide and move it so it sends the ball on a different path.

Quoted from Tablewicked:

Never had to clean it before, but I would try taking the ball off the playfield and spay with simple green and lightly scrub with a magic eraser. I would be cautious around the black parts, it might remove the black lines. Good luck!
