I've screwed in the hex bolt on the reverse switch and it seems to have cured the problem for now. Makes sense, since the number quadrant wasn't always backing up enough to let the solenoid plunger release. Thank you for your insight!

I've read section B of the manual a few times now, and it's only beginning to make sense, so I haven't checked any of the switches yet. I'm not even sure what to look for, or if I need to take the machine apart to get to it. I'm hoping I can make the adjustment via the two hexagonal bolts near the n...

I've tried a few things that haven't worked so far. I've taken a short video of the solenoid working and not working: Jamming solenoid plunger. For some reason, the plate doesn't reverse, so the plunger doesn't return to the up position. It stays wedged in the machinery: https://youtu.be/Huf7mz64UA4...

Ok, that is different. What is happening is that the rocker is getting wedged inbetween two pins. -Over time the indexing of the rockers (hammers) becomes a bit sloppy, the hammers to get wedged between two pins. Sometimes this can be dealt with by tightening-up the clearances of the nylon guide ro...

I've also noticed that when you hear a distinct buzzing sound in the beginning, the solenoids usually release. When you don't hear that buzz, they usually stay wedged in the machine.

Above is the stuck number 1 solenoid, and in the photo below you can see how the solenoid is wedged in the machinery.

Here is a photo of the stuck number 7. When the number 1 sticks, I can get a photo from the underside as well.

My last bit of troubleshooting is to address the sticky number solenoids. At first, I thought they might be gummed up with something,...
