All right, I have two questions:

1. I have rebuilt my Swamp VUK - new coil, coil sleeve, and spring. My playfield had some pretty nasty holes for the mounting hardware, and I had to use wood filler to make it to where all my hex screws could be used to mount my under playfield hardware. When my Swamp VUK fires, the ball pretty much always deflects off of the right slingshots - not enough to trigger the slingshot coil, but it will hit it and deflect to the left flipper.

How do I "adjust" the VUK ? Do you loosen the mounting hardware and adjust up and down/side to side (directional...not actual depeth to and from the playfield)? Do you "tweak" the coil bracket or the VUK scoop? I hear people "adjusting" the VUK, but I don't know exactly what that means.

2. I had to replace my trough arm responsible for launching balls out of the ball trough and into the shooter lane - all new hardware, and it works like a champs now. Unfortunately, after kicking a ball into the shooter lane, the trough arm does not go down far enough, and that hangs the other two balls up from rolling down into place where they should be in case I start locking balls.

What is the best way to adjust this? Add washers between the trough arm mounting hardware and the playfield? Get a shorter spring that will pull the arm further down and if so, what would you recommend (I used the spring outlined in the manual, and this is where I am now) ? Bend the arm so it is lower?

Ok dok, got the 2nd one nailed. What it ended up being - there are 4 screws that hold the trough arm to the underside of the playfield. One of the 4 screws was interfering with the trough arm, and the arm was not able to return to its resting position. Finally just happened to see the arm resting on the screw head and I moved it and saw it return that extra space I needed. So that is solved!

Haven't got to #1 yet. Been working on this all day with some other projects around the house, and am taking a couple mins break before resuming work.

I got it to where the ball ricochets off the right slingshot to the left flipper 9/10 times. I tried adjusting the VUK by hand to see if I could even get it to fire to the right flipper. Did my very best, and I just could not make it happen. I'll try again down the road. Totally baffled that I could not get the VUK to fire it in the correct spot...
