Are you sure that the switch is adjusted properly? I had this trouble with mine. Its kind of a pain to get set just right but if its not opening and closing as it should it won't reveal when its supposed to. You will have to operate it "manually" and watch the switch closing and opening and stop it at the right position.

Is it scoring when its shot all the way? I had to clean contacts on mine recently because it wasn't recognizing shots anymore and hanging up at times. Cleaned contacts and it was good to go again. I've never had to adjust it however

Oh, its not revealing when you make the vari-target. The switch on the rotating robot shield cover thing has to be adjusted ever so perfectly. I forget off hand if its supposed to stay open all the way around then close and then open the switch again when its covered again. Mine didn't work right when I got it and I had to F with it for what seemed like forever to get it just right.

I hope that means you got to play mine at MGC I had the one with the clear ramps.
The thing I like about the system 80B machines is they seem easier to move. loading up at MGC rather than wait on the loading dock I took it in the elevator and over the skywalk then down the elevator and through the lobby of the hilton and out to the parking structure. If Genesis doesn't fit in your vehicle I don't know what will.

I got that Genesis in St Cloud, MN a couple years ago they are out there if you are willing to drive. I messed around with flipper adjustments quite a while to get it hopefully challenging but able to hit the ramps if you work at it. I'm curious to know how it played I set it easier with the drops to hopefully make it more fun for casual people.

You have a screw missing on the coil stop in the upper picture. I had to adjust the flipper bats multiple times to get it just right you might have to clean the shafts with a file or reverse them to get it to stop biting down the bats in the same (bad) position. Keep playing it and adjusting eventually it will get where it needs to be. You should be able to make the left ramp from a cradle but I normally just shoot drop targets and the vari target from the right flipper. I found that its easier to backhand the left ramp from the left flipper since I always seem to get ball drains from using the left flipper to shoot the drops.
