I'm very new to pinball repairs. I've worked at a small arcade for several years and learned a lot from trial and error but have no actual training on any of this.

I took this video showing the problems with the flippers (a short 26 second video posted to YouTube)

It appears to me that they are stuck for different issues. I believe I've narrowed it down to be mechanical, as they don't go back to their normal spot when I turned the power off. But the left one tries to activate still but just can't seem to move. The right one just gets stuck at the top and doesn't seem to do anything else at all until it gets shaken or bumped hard enough to fall back into home position.

I've already replaced the main parts of the right flipper, but it doesn't seem to have been the problem. The image shows the 3 parts I DID already swap out on the right flipper; the plunger, the sleeve, the flipper link. I didn't think the larger metal part was the problem. It worked again for a couple of weeks but now is getting stuck again.

Now that the left has it's own issue, and the right side is repeating its problem, it's clear I've made a mistake somewhere.

Any tips of what to swap next or what else I can do to fix it?

Wow good call on the coil stops being the culprit. MaxIsDead IMG_0338 (resized).jpg IMG_0339 (resized).jpg The left side was pretty bad and had started mushrooming the plunger as well. It's crazy how loose the ends of them were. I wouldn't have known they were supposed to be essentially riveted flush, because both were so bad and wobbly I might have assumed they were supposed to be wobbly for tolerances or something. I swapped out the coil stop on the right side that had already had the plunger and link replaced, then did the whole procedure to the left side as well and so far everything seems to be working!

Mad_Dog_Coin_Op I'm curious where you mean I need to leave a little bit of up and down travel, is this picture enough to show you what you wanted to see? Where exactly do I want that play? While they are working now, I'd much prefer to position them better so they run as smooth as possible.

Thanks for the help, you guys are all awesome!
