This is actually not on my KZ tube... it's the valve stem on a TPMS valve on my car. When I go to remove the valve stem core, it turns counter-clockwise until the small bar which the valve core tool grabs is almost flush with the top of the stem. Then it just spins. I can turn the core back in all the way using the valve core removal tool, and it seats fine (when it stops turning, that feels "normal"). I can air-up the tire and let air out as normal. Just can't remove the core.
Wondering if I should try working some silicone spray down into the core. I plan to pull the tire off the wheel, but it's going to be a pain, with the core stuck in there.
