Finishing up a 60 hour restoration of an IJ. During playtest, experienced a troublesome mode start saucer that would reject the ball 9 times out of 10.
Super frustrating as this isn't the easiest shot to line up in the first place and then when you finally nail it, you get rejected.
Not what the designers of this game intended I think.
Did some research here and found some potential fixes but all seemed problematic in that you either needed a bunch of steps to complete to accomplish and / or
you had a risk of breaking the plastic sitting above the hole and or smashing the nearby opto on the adjacent ramp.
The ultimate fix was relatively easy to do and I am proud to say this hole now grabs the ball 9 times out of 10. Like a catchers glove in fact! =)
I took out the angled metal back stop and relocated it as far as it would go up against that back metal wall. Ground off the area of the metal back stop that was peeking out under the wall / that was sticking out past the metal wall during trial fitment. Filled in the original playfield holes with wood glue coated bamboo skewers pounded in and cut flush with the playfield. Screwed down the metal backstop in its new further back location and added a blue sticky backed bumper to the backstop.
