How to remove Kohler Memoirs faucet handle (and replace cartridge)?
I'm in the same predicament here. I removed the set screw, but can't get the lever to pop off. I've tried several iterations of WD-40 and vinegar/water in the set screw hole. Has anyone actually ever been able to do this (with this or similar Kohler model) and/or have a picture of it? More on reddit.com

May 8, 2023 -

I can’t get this cold water faucet cartridge loose, it feels completely stuck. Tried with a ratchet, extra person holding the faucet in place, used CLR, nothing I tried works. What am I doing wrong? I don’t see visible rust so I’m surprised it’s so stuck. Please advise. Thanks!
