well, maybe, but i took them all apart and lubed them all just prior,, and i think it was doing this before i put loctite on the grub screw. it doesn't just stick really, it gets progressivly harder to to push it as it nears the pin on one side. this is why i think somthing's warped, it's the cylinder/socket connection that's probably dragging for half of its full motion

but, i'll take it apart again, see what happens
