Picked up a new to me (used) Dillon 1050.

I can’t for the life of me get the primer bar to reliably slide all the way forward and index properly with the shell plate.

I have
* Deep cleaned the bar and the slot it rides in
* Removed the assembly with the arm and cleaned it and reset it per Dillon’s instructions
* ensured the tool head is tight
* played with 800 different heights on the arm assembly

I’m at a loss on what to do next, and Dillon support wasn’t super helpful as they just asked if it was clean :(

Please gunpowder Wizards of Reddit, tell me what spell to cast next.
