I have 2 3w stories,

I bought a used 3w 85. the engine leaked all over. I sent it to cactus avaition and he fixed it for free. Turns out the original owener took it apart and didn't put it back together correctly.

I also bought a 3w 100 used (old style). the ignition went out. Once again, Cactus repaired it for free under warranty.

that is 2 motors that he never sold me that he fixed, for free. that is good service.
