Reviving an old thread instead of making a new one to keep the conversation going about something that needs to be dealt with at Stern.

I'm on my 2nd NIB Stern in a row where the auto plunger is just weak. Straight out of the box, my Avengers Premium barely made it all the way around the orbit/ramp, failing maybe 20% of the time. And now that I've got maybe 50 games on it, it's down to below 5% success rate. It's just too damn weak.

Previously I had a Jurassic Park that, in the same way, was about a 80% success out of the box, then dropped to near 0% success VERY quickly. These are home use games, not played very hard at all. And once those auto plungers start to miss, it doesn't matter if the game is booting up for the first time, or the coil has been fired 25 times in a half hour, it just sucks.

I've tried it all - bending the forks, doing the velcro trick, coil sleeve replacement (this shouldn't have to be a thing at such low plays, but whatever, tried it).

Has anyone made any progress on improving this issue? I'd be willing to buy the parts and rebuild it however necessary.
