Seems after 2 days of play my elevator got worse. Was only a minor issue now today it was every damn ball. So I decided to look into the elevator more. I've put the washers in mine did not help at all. I do not think my ball was hitting the screws anyways.
So after playing with mech in test mode for awhile and seeing what exactly is causing the issue I came up with a fix for my machine.
When the divertor coil is active and pulling down the divertor while all they way down I noticed the whole divertor area was very loose and rattling, and not really down all the way, if I put just slight pressure on the divertor with my finger it would pop out no problem.
All I did was bent the 2 arms that pull down the divertor assembly just a bit down on each side with some pliers. Did not need to remove the mech at all, just be careful not to slip and mess up anything else.
Not for sure if this is the issue will all the elevators that have issues but it did fix my machine and now the ball flies out of the divertor to the upper playfield.
Attached is a crapy picture of mine. You can see the arms slight bent down.
