Quoted from Tranquilize:

While this bandaid may work, it is not the correct solution. Your flippers should barely need springs at all. If the spring is not pulling it down, you should find the cause of the unwanted friction. Friction wears on parts quickly. Fix it correctly and be done with it!

It would be highly unlikely in such a new game to have issues with the plunger or sleeve for wear unless it was assembled incorrectly.
I’ve had to replace two springs on a friends Guardians. One just snapped in the middle which was bizarre. The other side was a off in its size and appeared to have reduced elasticity. (The left flipper return to rest was lethargic) Maybe, it was a shitty batch from their vendor or just the wrong ones. Who knows? However, the spring is something that is to be looked at and thought about as perhaps a problem and not a band-aid fix or a incorrect solution.

Quoted from imharrow:

Do not assume it was correctly assembled. I know someone who spent weeks trying to track down an issue with stern. Eventually brought it back to their distributor to debug. In the end it was a complete catastrophic failure of the coil stop. Rivot completely failed and the stop was detached inside the coil. Destroyed the entire assembly.
They never took it apart because it was brand new, no plays when the problem started. I recommend assuming everything is faulty until it can be shown to be correct.

I said it might be incorrectly assembled. I’m also pointing out failure of parts

Quoted from Tranquilize:

If we're arguing that the spring is defective or the incorrect size, then yes, the spring should be replaced. From what I understood, the fix posed was to replace a correct spring with a stronger spring. As for the sleeve and plunger, sometimes even a slight angle in the way a screw was screwed into the PF can cause the direction of the plunger to be off, hence causing friction. You'd see this in the sleeve right away. On a new game, the wear would be minimal, but with a bright light, you'd see it. I'm only suggesting that a close check for friction has fixed this type of flipper issue for me 100% of the time with a working spring. I'd guess that I've come across the issue about 20 times or so.

Yes, obviously if a coil sleeve is fubar, screwed in wrong or the stop is loose and their is gold colored dust in the cabinet it should be replaced.

To clarify, Stern does use & have stronger tension springs. I know, because they sent me the same size / length and it was more robust, they were a little less thin than what was on the Guardians that had problems. It’s been a few months since the new thicker springs and it has no issues since the swap.
