Quoted from SAM1978:Hey JPP fam, I've had my Pro for about 2 years, and in the last few weeks I've noticed it's playing a little rough. Specifically I've noticed the orbit around bumpers has sounded progressively worse. A pronounced "klunk" when the ball circles through it. After some investigating, the pop-up post is sitting a little higher than the playfield. Has anyone made adjustments to one of these? I can't find much in the way of documentation on how to adjust. I'm also noticing shots are getting much more airborne than I'm accustomed to. This was my first machine, and learning the ins and outs of maintenance as I go. Any tips, things to look into?
I clean & wax as needed (monthly/depending on plays). New rubbers + clean pinballs, are coming on Friday, I figure that can't hurt.
Its a microadjust stopper on the coil stop for that post. Just dial it down and u should be set.
