...I bet no one has used that subject before.
Anyway, I made my first pinball machine repair! Two actually. I replaced the (uncolored) launcher spring with the appropriate Red spring. But that was not complicated enough to call it a "repair."
The main event was the replacement of the upper right Flipper Assembly (I ordered a brand new, complete assembly, figuring I could rebuild the old one and have an extra). While I was at it, I ordered three new bats and new red flipper rubber (I have yet to replace the two lower bats). It's a good thing I did too, because I believe I discovered what was causing the magnet shot to fail. The upper bat was cracked... basically shredded... under the rubber.
It was fun to make the repair, and then have the shot work every time! Reminds me of my days working on cars.
