Hi guys, first Pinside post, long time reader.

I'm renting a Willy Wonka CE for the next few months (how good is it!) and every other game, the Gobstopper advance multiplier goes into a random triggering frenzy - usually when lock is lit (hole is open). Sometimes vibration makes it happen, either from the shaker motor or flippers/bumpers, other times it'll just do it by itself. Of course the shaker fires when you hit the switch, so it ends up going crazy. When you lock a ball, it stops.
You reckon it's something easily fixed? I'm not much of an engineer...

Cheers in advance!

Thanks Zaph, I'll give it a go - other thing I've noticed while investigating is the Gobstopper spin motor is a bit noisy and appears to be grinding/struggling on the low speed. (first lock)
It's just as noisy at faster speeds but that's because it's higher power/spin. Anything that can be done about that? The bottom of the toy is clear, just seems that the motor is a bit grindy... Thanks for your help!

Hi guys, my Gobstopper target is intermittent AF. Sometimes it works perfectly, sometimes it never works, and sometimes it triggers in a frenzy of a thousand hits (without actually hitting it - usually when the lock is open and also can be triggered by tapping the flippers ie vibrations).
Any ideas? I don't think it's the microswitch because you can sometimes literally touch it with your finger and it still doesn't do what it's supposed to.

I've also got a noisy gobstopper but I think I can fix that.

This is a rental machine and I've noticed the last guy has tightened the spring on the bash thingy - obvs to get it to trigger less.

Rental guy has offered to send out a tech to fix it, but I'll see if I can do something about it via you guys first

We watched the movie tonight.
Loved hearing the callouts etc... Gene Wilder died in 2016, makes me sad he never got to see the Pinball, he would've been absolutely thrilled.
